Question

Why are magnets dipoles?

Answer 1

Any magnetic system we shall see has a north pole and a south pole associated with it. The magnetic field originates from the N pole and terminates in the S pole. This two pole system is called a magnetic dipole.

Explanation:

So far, all magnetic systems are magnetic dipoles.

Magnetic monopoles are not known to exist. Even though they might have existed sometime in the past.

We simple can't isolate the N and S poles of a bar magnet by cutting it into two pieces. A new N and S pole are generated.
