Question

whai is magnetic dipole

Answer 1

A magnetic dipole is the limit of either a closed loop of electric current or a pair of poles as the dimensions of the source are reduced to zero while keeping the magnetic moment constant. It is a magnetic analogue of the electric dipole, but the analogy is not complete.

Answer 2

Answer:

All magnets have both a north and a south pole, which classifies them as dipoles. It is impossible to create a magnet with only one pole. Similar poles always repel each other, and opposite poles always attract.

Magnetic dipole moments have dimensions of current time's area or energy divided by magnetic flux density. The exact unit for dipole moment is ampere-square metre when it comes to the metre–kilogram– second–ampere and SI systems.
