Answer 2

Potential energy will be U= mBcosθ.

Potential energy of magnetic diopole suspended freely in magnetic field can be defined as the amount of work that needs to be done in rotating the dipole from zero potential energy position to some desired position.

Net magnetic force on the current loop is zero but it does experience some torque.

Equation through which we can calculate the magnetic potential energy of a magnetic dipole kept in a uniform magnetic field is

U= −m⃗ .B⃗

U= mBcosθ

where U is potential energy, m is magnetic moment of the dipole, B is magnetic field
