Do help!

Answer 3

it is the intrinsic property of a magnetic dipole..

if the magnetic dipole moment is high, then the magnetic field due that dipole would be high, its directly proportional to it!

Answer 4

Imagine a big bar magnetic, Which have a magnetic North and South, now divide the bar magnetic in half and half till you reach the molecular stage, That small magnetic is called a magnetic dipole Since This magnetic dipole a net magnetic field very similar to electric field this magnetic field is called magnetic dipole moment ( 2ml or Simply M). If you want derivation how it come ASK........

Answer 5

Please explain this point:
"The magnetic moment of a magnet is a quantity that determines the force that the magnet can exert on electric currents and the torque that a magnetic field will exert on it. A loop of electric current, a bar magnet, an electron, a molecule, and a planet all have magnetic moments."

Answer 6

if you keep a current carrying loop kept in a uniform magnetic field , then the torque acting on the loop is given by the equation

\[\tau = \mu \times B\]
so if B is unity and angle between the normal to the coil and the field is 90 degrees (so the plane of the loop is along the field) THEN,
mu = Tau

hence we define magnetic dipole moment as the torque acting on a current carrying loop kept in a uniform magnetic field of unit strength parallel to it!

Answer 7

What about a bar magnet in a non-uniform magnetic field.
How can we relate magnetic dipole moment to it?

Answer 8

And form that equation of torque, how can we relate it to magnetic potential energy: \[U _{PE} = \mu \times B \]

The magnetic potential energy speaks generally of each magnetic field of all kinds of things like a magnet,loop of wire,planets etc...
