Question

Describe an enperiment to show that we can get electrical energy by using a magnet?​

Answer 1

Explanation:

Put a bar magnet in a tube, if you know what a Smarties tube is that will do very well, and make sure the magnet is not small enough to get lost in the tube but not big enough to get jammed; you want it to be able to go up and down nice and cleanly. Now wind some copper wire round the middle of the Smarties tube...

hope it will be helpful for u..❤❤☺☺☺
