What is a magnetic dipole moment?

[dani-1]

i want to learn about magnetic dipole moments but don't have a good grasp on it

Ummm... ok. Griffith's text on electrodynamics is a good reference.

Hi,

You consider circular wire through which some current is flowing.As you know that moving charge creates magnetic field surround it.
Now you will find two poles as north and south pole which behaves as magnet.(according to right hand thumb rule u can find in which direction (w.r.t the loop) the poles are).
Magnetic dipole moment is the product of the area enclosed by loop and the strength of current in it.
It's a vector quantity.
