Question

How will you make an electromagnet in the laboratory

Answer 1

Use a pair of wire strippers to remove a few centimeters of insulation from each end of the wire. Neatly wrap the wire around the nail. The more wire you wrap around the nail, the stronger your electromagnet will be. Makecertain that you leave enough of the wire unwound so that you can attach the battery.

Answer 2

An electromagnet can be made in the laboratory by the following steps -

• At first we need to gather the following things -

1) A small (finger size) iron nail.

2) Non-insulated copper wire.

3) Battery.

• At first rub off the dirt or rust on the surface of the iron nail.

• Then wrap around the copper wire on the iron nail for 75-100 rounds.

• Connect the both ends of the wrapped copper wire with the positive and negative terminals of the battery.

• Then the iron nail will become an electromagnet.
