Question

describe the procedure of making electromagnet
​

Answer 1

Answer:

Electromagnets can be created by wrapping a wire around an iron nail and running current through the wire. The electric field in the wire coil creates a magnetic field around the nail. In some cases, the nail will remain magnetised even when removed from within the wire coil.

Answer 2

A simple electromagnet can be created with the help of a coil of wire wrapped around an iron core. A core of ferromagnetic material like iron, which serves to increase the magnetic field created. The amount of current through the winding is proportional to the amount of magnetic field generated.
