Question

What would be the dipole moment if two bar magnets are making 30 degree angle

Answer 1

when dipole moment of two bar magnet making at 30 degree it means the dipole moment will decrease by 1/2 because dipole moment is directly proportional to the angle formed by the two charge.

Answer 2

Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces.
