Home Electricity. Wiki User A magnet alone can not light up a light bulb. There has to be some additional components used to harness enough magnetic energy to light a bulb. It also has to be focused to the correct connectors of the light bulb. EX: Find a strong cylindrical magnet and attach it to a non magnetic rod i.
Build a cylinders housing slightly larger than the magnet with one end open to allow the magnet to be placed inside the opening i. Wrap electrical hobby wire bare copper wire around the housing many, many tines. Attach the ends of the wires to a small light bulb. When the magnet is inserted into the housing and spun it will light up the bulb. The faster is is spun the more energy is collected.
Also, check out the SEG generator using magnetic energy to power houses. To make a light bulb light connect it to a coil of wire and then take a permanent magnet and wave it by the coil of wire. The flux from the magnet will cut the coil of wires and induce a current to flow in the wire.
The bulb should glow each time the magnet passes the coil. You can not. There is additional equipment needed.

A closed wire circuit is needed in order for the current to flow and light the bulb. With this circuit in place a magnet should be able to induce a current into the wire as the magnetic flux of the magnet passes by the wire.

A moving magnetic field causes an electric current to flow in a copper wire. This current will light a bulb. Asked in Science How much volage does a light bulb use? Asked in Home Electricity Why do you have a light bulb?
Light bulb provide electrical light. Asked in Compound Words Is light bulb a compound word? The light bulb is two words, not a combination of light and bulb. Asked in Electricity and Magnetism How do you generate a light bulb with magnet wire so it makes electricity? This may take quite a bit of effort, as most incandescent light bulbs use a fair bit of current. Find the smallest bulb with the lowest operating voltage, from a small flashlight. Get as many turns as you can from your piece of wire, wrapping it around and around.
Connect the bulb across the ends of the wire.Dissolved sugar is not an ionic solution and hence can not transport electrons, so it can't pass a current of electricity. Do you propose makes the bulb easy? The circuit many times encompass a easy build linked to a electricity source dry cellular? If the textile between the probes habit electricity, the bulb lights.
This ions enable electricity to habit. Such recommendations recommendations that incorporate ions are referred to as electrolytes.
The salt, when water is added, has ions particles with a positive or negative chargewhich conduct electicity. Sugar does not. Electricity is the movement of electrons through a conductor. If you are moving it through something without electrons that are easily moved, it will not conduct as well as something that has lots of ions, like salt water or copper wire.

Get your answers by asking now.Lighting is something that we take for granted in the developed world, but there are still many areas around the globe where people lack reliable access to light at night. They often use kerosene lamps, which contribute to indoor pollution and have to be refilled with oil regularly. Aisa Mijeno, an engineering professor who worked for years with Greenpeace Philippines, noticed during her work there that many indigenous people in the over-7, islands that make up the country were using kerosene lamps exclusively for lighting.
The family she lived with there would have to climb down the mountain that they lived on and then walk an additional 30 km to the nearest town in order to get more oil to fuel their lamps. Mileno wanted to come up with a lighting solution that was both better for the environment and made the lives of the people better and easier. Mileno told Core 77"A few of the common things we noticed in marginalized island communities are the staple supplies of salt, water and rice.
Almost all of the household we have been stationed in consist of these common elements in their homes. With that in mind, she developed an LED lamp that runs on salt water -- one glass of water and two tablespoons of salt to be exact. And as Gizmag explains, the lamp also relies on a galvanic cell battery with two electrodes placed in the salt and water electrolyte solution.
The SALt lamp stays lit for eight hours a day with the salt water concoction, or for coastal populations, sea water, and can run everyday for six months until the anode wears out. If it is used in tandem with another light source or for less time every day, it will last for more than a year. The lamp uses the same science as that behind the Galvanic cell, which is the basis for batteries. The start-up said in changing electrolytes to a saline solution it makes the lighting non-toxic and a safer choice by removing the risk of fires from tipped over lamps and candles.
It's healthier for the people using it because the lamp doesn't emit indoor pollution and the materials used are far better for the environment. The lamp can also be used in emergency situations as both a lighting source and an energy source for charging phones with a USB cable. There is no price set for the lamp yet, but they are letting people sign up for pre-orders on their website. SALt plans to have the lamp out by the end of the year or early next year, with a focus on getting it into the hands of the communities and NGO's that need it most.

Tape one end of one wire to the highest point of the aluminum foil, and the opposite end of the other wire to the magnet. Third step: interface one of the cathode wires to the positive terminal on the light switch; and the second anode wire to the negative terminal on the light switch. Fourth step: Insert the two cathodes into the salt water. They ought to be on either side of the measuring glass. When this is done, the light will illuminate.
Conductivity is the capacity of an answer for convey electric current. In fluid arrangements, the electrical flow is conveyed by charged particles. The conductivity is dictated by the quantity of charge bearers, how quick they move, and how much charge every one conveys. Subsequently, for most fluid arrangements, the higher the centralization of broke up salts, which will prompt more particles, the higher the conductivity. Salt water is comprised of Sodium Chloride and water.
At the point when salt is added to water, the Sodium and Chloride particles drift unreservedly in the water.
Since a particle has an electrical charge, it can bring power through water. Chris Holroyd is a tech magazine writer who has been extensively writing in the technology field for a few years.

Forums Engineering Electrical Engineering. Saltwater and light bulbs. Thread starter mutzy Start date Feb 4, Hi everyone. Today in chemistry we saw this really cool video about different chemical reactions and learned that saltwater conducts electricity. I have one of those light bulbs that came out of a flashlight and it has 2 wires coming out of it. If I had some saltwater and stuck the wires of the bulb in the water would the bulb light? If so how can I do this so I won't get electrocuted?
Also does anyone know how much power saltwater produces? Last edited: Feb 4, Related Electrical Engineering News on Phys. Integral Staff Emeritus. Science Advisor. Gold Member. To light the bulb you need a current, this means there must be a potential difference across the leads of the bulb. Sticking the bulbs in salt water does not imply a potential difference. Quite the opposite since the salt water is a good conductor, the leads will be at very nearly the same potential.
Similar to connecting a wire directly from one lead to the other, this is not how you light the bulb. Now, If you were to place 1 lead in salt water and connect the other to a battery.Technology for electricity has evolved over time, but the basic principles of positive and negative charges can be demonstrated by creating a simple battery with supplies around the house and from a small electronics or home improvement store.
Also known as an air battery, a saltwater battery uses the positive and negative ions from salt in water to generate a small amount of energy, enough to power a small, low voltage light bulb.
Metal electrodes can be fashioned from metal nails that are long enough to extend past the water line of the solution.
Position your light bulb base at one end of the wooden board, leaving room on the other end for the ceramic cup. Secure the light bulb base by attaching screws to the base and tightening with a screwdriver. Do not drive the screws flush into the base; instead, leave the top of the screws exposed so that you can attach alligator clips. Cut two equal lengths of copper wire, so that each can extend from the light bulb base to the ceramic mug.
Strip the coating from each end of the wires and attach alligator clips to each. If desired, connect one color of alligator clips on each wire, so that one wire has two black ends and the other has two red ends. Place the iron nails in the cup filled with saltwater solution, taking care that the nails do not touch each other and are not submerged. Clip one end of one wire to the exposed top of one nail and clip the other end to one screw of the light bulb base.
Detach the alligator clips from the light bulb base and clip to the connectors on a voltmeter, if desired, to measure the voltage from your saltwater battery. Build a stronger battery by using a larger container non-metal and doubling the ingredients for the saltwater solution. Make sure the ends of your iron nails are above the water level suspend with paper clip if needed. Consider connecting a small buzzer or clock, instead of the small light bulb.
Avoid spilling the saltwater solution near your components. It can create a short. Use containers made of materials that are poor conductors of electricity, such as ceramic or plastic. Do not use metal cups, bowls or containers. Regina Edwards has been a freelance writer since She has penned video scripts, instructional manuals, white papers and abstracts.
She has also ghostwritten diabetes journals. Edwards is a scuba instructor and Usui and Karuna Reiki teacher. Insert the light bulb into the base and twist gently to tighten. Repeat step 7 for the other nail and the other screw on the light bulb base. Things You'll Need. About the Author. Photo Credits. Copyright Leaf Group Ltd.With all the terrariums and plant growing bulbs on here, let's do something different. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson.
Once you have all your tools, hollow out the bulb. Look at the bottom of the bulb and notice the solder point Pic 1. This is held to a layer of non-conducive glass by a metal disc. After that, pull up on the metal disc and break the copper wire that is attached to it. After this you should be left with the glass "dome" of sorts that protects the bulb pic 4.
The black glass is very sharp and sharp shards of glass hurt, so take caution. After you have a good view of the back fill tube, take your screwdriver and stick it next to the back fill tube Pic 8 and push down.
The wedge of the screwdriver should break the fill tube and you should hear a small pop. This is air rushing into the previously inert gas filled light bulb. The fill tube should just shake out of the bulb Pic 9. Now you should have a clear view of the bulb innards if you look down the small opening Pic 10 What you're going to do from here, is use any implement you have to slowly chip away at the inner bulb.Free Energy Experiment Using salt and water - Free Energy bulb -
I used a long screwdriver to get down in there and slowly chip away at the glass. When you have a big enough hole to pull the filament out, stop chipping. Pull out the filament assembly Pic 11 and pull it off with the pliers Pic Carefully shake out the glass shards.
Now, your bulb will probably look a bit scratched up Pic 1. This is from the glass shards scraping the white powder called "Kaolin". Kaolin is a non toxic dust they use to frost the inside of the bulb. If your bulb doesn't look scratched up, you might have an acid etched bulb, which means the frosted effect is built into the glass.
More on Kaolin here. There are many ways to wash the inside of the bulb. Many people say salt works, rice, a bit of sand, but I find that water works the best and is less wasteful. This may have to be done a couple times to get all the kaolin out. A clear bulb is what we're going for here Pic 4. Any left over white can be cleaned with a napkin and a small piece of wire. After hollowing and cleaning the bulb of any kaolin, grab the electrical tape and wrap the metal screw of the bulb a few times making sure to press the tape into the grooves and wrap the OPPOSITE direction of the screw.
We wrap the opposite direction so that when we place the cap on, the tape doesn't get in the way of the cap. Light your heat source I used a candle 2. Take your pliers and grab the nail 3. Heat the nail until hot 4. Stab the cap with the nail a couple times The amount of holes and the width of them is completely up to you.
Something you have to keep in mind is that you have to make the holes big enough for standard table salt to come out of so you may find yourself widening them. I ended up taking the end of a coat hanger and heating it and using it to widen the holes. Now it's time to fit the cap.
