Question

potential energy of a bar magnet of magnetic moment M placed in a magnetic field of induction B such that it makes an angle theta with the direction of B

Answer 1

Answer:

P = -MBcosθ.

Explanation:

The potential energy of a magnetic dipole moment is given as P which is equal to the negative product of the magnetic moment with the magnetic field B with the cos component of the angle θ which the magnetic moment and the magnetic field is making.

So, the potential energy is calculated by the formulae of P =  -MBcosθ.
