Question

When an electric current is passed through a solenoid it acts as a/an a) Insulator b) Resistor c) Electric bell d) Bar magnet

Answer 1

When the electric current is transferred through the solenoid, it gives the magnetic lines of forces similar to a bar magnet, so BAR MAGNET is the right answer. Here one of the solenoids acts as the magnetic north pole, and solenoids at the other end act as the magnetic south pole.
