Question by Hannah: Hi is anyone good at physics in science about electricity?
Hi
my question is
how do you make electricity using a magnet and wire,
please help me
thanx

ps all comments appereciated
Best answer:
Answer by Pythagoras’ worst student
bend the wire into a loop.
move the magnet through the loop
a changing magnetic field will produce a current in the loop
It’s all the fault of a bloke called Maxwell. So if you know any Maxwell’s tell them to go take a hike
What do you think? Answer below!
Take a strong magnet and some copper wire . Coil the wire. Two ends of the wire should be connected to a very sensitive galvanometer. Now move the col to and fro near the manet so that the magnetic lines of force gets diturbed. You can notice that the pointer of the galvanometer is deflected forward and backward. This is nothing but the electricity.
to tell you the truth, i dont think you will be able to make enough electricity to turn a regular light bulb on
1. You coil the wire up on say a small wooden stick, note its got to be insulated wire.
2. The 2 protruding ends of the coiled wire need to point out along the stick, and ensure they are held firmly on the stick.
3. Mount the wooden stick such that it can rotate – it can spin along its axis – held up at either end.
4. Mount the magnet just slightly away from the coil. Its better to have 2 magnets one each side.
5. Now mount 2 electrical connectors that just touch the end of the stick, the side with the 2 ends of the coil afixed to it.
6. Connect the electrical connectors to a lamp
7. Spin the stick,
8. Watch the lamp light up … WOOOOOOOO
The electrons in the wire get excited when they cut through the magnetic field. They get so excited they start to jiggle all in the same way, causing what we call an electric current running in the wire. They jiggle all the way along to the connectors and up to the lamp. (the lamp lights up…. thats another story)
