Question

Explain the method of preparing electromagnet how do you test the poles of an electromagnet with the help of magnetic compass

Answer 1

An Electromagnet can be created by wrapping a insulated copper wire around an iron ore (or any magnetic material like iron,steel ,nickle ,cobalt)

with electric current flowing through it.

By bringing a compass close to  a permanent magnet with labeled north and south poles we can check this concept.The end of the compass needle that usually points north will be repelled by the north pole of the electromagnet and attracted by the south pole.

Answer 2

i. Wrap Insulated copper wire around iron core and connect the wire to electric point.

ii. North of the compass will indicate the south magnetic pole.

Explanation:

i. A simple electromagnet can be made by using a copper wire, a material made up of iron, and an electric point.

Wrap the insulated copper wire around the iron core and connect it with the electric point.

When electricity will pass through the wrapped copper coil, magnetic field will be produced. The iron core increases the strength of the magnetic field. The strength can also be increased by increasing the number of turns.

ii. The poles of the electromagnet can be easily detected with the help of a magnetic compass. Bring the compass closer to it. The north on the compass will point towards the magnetic south pole and the south will indicate the magnetic north.
