Magnetic moment problem

How many neutral points will be obtained when a bar magnet is kept with magnetic moment parallel to earth's magnetic field ?

The dimensions of (angular momentum)/(magnetic moment) are

Magnetic moment of the lap

Magnetic moment of Fe is similar to that of

A magnetic of magnetic moment placed along the X-axis in an magnet field .Find the torque acting on the magnetic field

Magnetic moment of an electron in nth orbit of hydrogen atom is

Magnetic moment of an electron in nth orbit of hydrogen atom is

A: A system can have magnetic moments even though its net charge is zero. R: Magnetic moment is created by charges in motion.

Assertion: When radius of circular loop carrying current is doubled, its magnetic moment becomes four times. Rrason: Magnetic moment depends on area of the loop.
