Question

At large distances, a current-carrying circular loop behaves exactly like which elementary magnetic element in nature?

Options

• A magnetic monopole

• A magnetic dipole (a tiny bar magnet)

• An infinitely long solenoid

• An electric dipole

Answer 1

A current-carrying circular loop behaves exactly like a magnetic dipole (a tiny bar magnet) at large distances. It is the elementary magnetic element in nature, just as the electric dipole is the elementary electric element.
