Classical Magnetism + Magnetic Materials

SI unit of magnetic pole strength is

Determine the magnetic moment of a bar magnet of magnetic length 5 cm and pole strength 2A m.

Classical Magnetism 3 Magnetic field|potential due to dipole

The magnetic dipole moment of a bar magnet is directly proportional to volume of the bar magnetic . You are given a bar magnet of length I , magnetic pole strength m and magnetic dipole moment M . What will be the effect on dipole moment and pole strength if the bar magnet is cut into the two equal pieces ? (i) Along it length ? (ii) Transverse to its length ?

On equatorial line of bar magnet, what is the formula for magnetic field strength?

Two identical bar magnets of magnetic pole strength 10 Am and length 10 cm are placed 2 m apart such that their axes are perpendicular to each other. Calculate the resultant magnetic field at a point midway between the magnets.

The magnetic dipole moment of a bar magnet of geometric length 6 cm and pole strength 100 Am is
