HEYA MATE,
HERE IS UR ANSWER.
Thanks for asking this question.
Electromagnet:-
This principle comes in very handy in the form of an electromagnet. An electromagnet is wire tightly wrapped around a ferromagnetic core. When the wire is connected to a battery, it produces a magnetic field that magnetizes the core. The magnetic fields of the core and the solenoid work together to make a very strong magnet. The best part about it is that the magnetic force stops when the electricity is turned off! Try it yourself with this experiment:
What You Need:
5 feet insulated copper wire
6-volt battery
large iron nail
paperclips
What You Do:
1. Tightly wrap the wire around the nail to make a solenoid with a ferromagnetic core. If you have enough wire, wrap more than one layer. (If your nail fits inside the straw from the last experiment, you can use that solenoid instead of rewrapping the wire.)
2. Try to pick up some paperclips with the wire-wrapped nail. Can you do it?
2. Strip an inch of insulation off each end of the wire.
3. Hook up the wire to the battery and try again to pick up the paperclips with the nail. This time the electricity will create a magnetic field and the nail will attract paperclips! (Don’t leave the wire hooked up to the battery for more than a few seconds at a time – it will get hot and drain the battery very quickly.)
Experiment some more with your electromagnet. Count how many paperclips it can pick up. If you coil more wire around it will it pick up more paperclips? How many paperclips can you pick up if you only use half as much wire? What would happen if you used a smaller battery, like a D-size? Predict what you think will happen and then try it out!
I HOPE IT HELPS U.
