current is flowing in a coil it behaves like a magnet. If the current if flowing in anticlockwise direction it behaves like a north pole and if the current is flowing in clockwise direction it behaves like a south pole.
Magnetic dipole moment gives the effectiveness of a magnet.
Magnetic dipole moment depends upon the pole strength.
Magnetic dipole moment creates magnetic field.
Magnetic field at a distance ‘r’ from the center of bar magnet is -
B = k
2Mr3
Where,
M = magnetic dipole moment of bar magnet.
Magnetic field at a distance ‘r’ from the center of current carrying circular coil is -
B = k
2Mr3
Where,
M = magnetic dipole moment of current carrying circular coil.
The product of current (I) flowing in the loop and the area (A) of the loop is called magnetic dipole moment (μ),
μ = NI→A→
Where,
N= number of turns
Where direction of area vector will be same as that of the direction of magnetic field at the center of loop.
