Find the stable equilibrium position of a magnet in a magnetic field.

Assuming theta = pi//2 as the zero-energy position of a magnet in a magnetic field, show that the potential energy of a magent can be written as u =- vec(B) . vec(m) . Hence find the stable equilibrium position of a magnet in a magnet in a magnetic field.

The work done in rotating a bar magnet of magnetic moment M from its unstable equilibrium position to its stable equilibrium position in a uniform magnetic field B is

The work done in rotating a bar magnet f magnetic moment M from its unstable equilibrium positon to its stable equilibrium position in a uniform magnetic field B is

What are the conditions for stable and unstable equilibrium of a magnet suspended in a uniform magnetic field?

Stable equilibrium of a magnetic dipole in a uniform magnetic field will be at orientation when:

A bar magnet is placed in the position of stable equilibrium in a uniform magnetic field of induction B. If it is rotated through an angle 180^@ , then the work done is.......(M = Magnetic Dipole moment of Bar magnet)
