procedure on making electricity by magnets?

Answer 1

Creating an electromagnet. You can build one of these at home by wrapping a fine insulated electrical wire many times around a nail, and then hooking it up to a battery. The nail will be turned into a temporary magnet. The principle behind this says that magnetic fields are produced by moving electric charges (called currents). In this case, there is a current flowing in the wire wrapped around the nail, and it produces a magnetic field along the direction of the nail. The nail itself is not needed to produce this field, but helps to contain and guide the field so you can (for example) pick up some paper clips with it.

Going the other way, you can create an electrical current by using a changing magnetic field. You can show this using a small coil of electrical wire hooked up to a very small light. Take a bar magnet and move it back and forth through the middle of the coil. (It won't work if you just hold the magnet still, since it has to be a changing magnetic field.) You should be able to see the light turn on because of the current that is induced in the wire. This is the same principle that makes electric generators possible.

Answer 2

Purpose:
We wanted to find out if which magnetism the compass will respond to the compass or the wire.


Materials:
1 battery and battery holder
1 magnetic compass
1 piece of # 22 coated hook up wire, 80cm long
3 piece of # 22 coated hook up wire, each
20cm long
1 switch
1 steel bolt, 8cm x 6mm
3 No.1 paper clips


Procedure:
1. We connected the 80cm wire to the battery and to the switch. Connect the 20cm to the other side of the battery.
2. Unhook the 80cm wire and get the steel bolt
and wrap the 80cm wire around it. Make sure that you leave a little wire on each side so that you can connect it to the circuit.
3. After you connect the bolt to the battery, turn the switch on. When you have the electricity on, the bolt will become a magnet and if you did it right it will attract the paper clips.


Results:
The bolt can hold 2 paper clips, when the switch is on.


Conclusion:
We learned that if electricity goes through a coil of wire around a piece of steel like a bolt, then the bolt becomes a magnet, but only when the electricity is on.

Answer 3

A magnet is fairly a lot a medium with a merely constructive or detrimental (Percieved really as detrimental) cost. merely cost a chunk of iron with electrical energy, and bam, a magnet.

Answer 4

run a magnet by a coil of wire and it creates a current

Answer 5

yaa..thats very simple...just have two horse shoe magnetz...and a copper wire.....wind the wire arnd a copper sheet then with two terminals out ...move the magnets in a very quick manner itz better if u have...a old motor from....some electronic car....then check....with a zero watt bulb....itz ready\!
