How to Make Electricity With Magnets
Everyone knows that magnets have both positive and negative charges. Most people also know that the positive charges are attracted to negative charges. There is a relationship between electricity and magnetism which has been studied by several scientists. Magnetic fields are produced by moving charges or current if you will.
Moving charges are directly affected by magnets, stationary charges however do not produce magnetic fields and stationary charges are not affected by magnets. If you were to take two wires with current flowing in them and you place them next to each other, they may attract or repel each other like two magnets would. This all has to do with moving charges.
The magnets that you have on your fridge or for other uses are simple examples of natural magnetic fields.
The Earth itself has a very big magnetic field. The core of the earth is filled with molten iron. Because of this the Earth's magnetic field protects us from space radiation and solar winds. When you look at an ordinary small magnet it is acting in the same way. The magnet has a field around it. In the next paragraphs you will learn how to magnets are connected with electricity and even how you can produce electricity using magnets.
According to the fundamentals of physics, when a closed wire cuts a magnet's field lines, the electrons in the wire experience an electromotive force (emf). From this principal, you can generate electricity with magnets using little more than household items. Spin a stack of magnets right next to a coil in a circuit to make an emf in the coil that oscillates back and forth, creating an alternating current (AC). The more turnings in the coil, the more emf the circuit will experience. To increase the number of turnings, use thin wire.
Now we will show you step by step how to create electricity using magnets.
Fold two close creases into a 6 x 12 inch piece of cardboard. The creases should be a little wider than the magnet you've selected.
Fold two more close creases about 4 inches away from the first two creases, making them as far from each other as the first two were. The cardboard should now overlap itself, making a four-sided enclosure.
Punch a long nail all the way through the center of both sides of the cardboard.
Tape a magnet to the nail on the inside of the enclosure. If you can't reach the nail inside, cut away some of the cardboard (this won't effect the outcome). An ideal magnet size is 1 inch by 1 inch by 1/4 inch. You'll be spinning the nail to turn the magnet, so a light small magnet is preferable.
Wrap thin insulated copper wire around the enclosure, looping it all in the same direction, with the windings all parallel to each other. The windings can overlap and be on both sides of the nail. The winding count can go into the hundreds. The more windings, the stronger the emf acting on the electrons in the windings.
Scrape the insulation off the two ends of the wire wrapped around the cardboard encasement, and attach the bare ends to the two contact points on an electric bulb with electrical tape. (The two contact points on a light bulb are the metal tip and the metal screw threads.)
Spin the nail and watch the bulb light up. You are now generating alternating current.
