A short bar magnet of magnetic moment 0*4JT^-1 is placed in a uniform magnetic field of 0*16T . The magnet is in stable equilibrium when the potencial energy is

A short bar magnet having magnetic moment M=0.80 JT^1 is placed in uniform magnetic field of 0.30 T. If bar magnet is free to rotate in plane of field, then (where U is potential energy and tau is torque)

A short bar magnet having magnetic moment M=0.80 JT^1 is placed in uniform magnetic field of 0.30 T. If bar magnet is free to rotate in plane of field, then (where U is potential energy and tau is torque)

A short bar magnet having magnetic moment M = 0.80 JT^(-1) is placed in uniform magnetic field of 0.30 T.If bar magnet is free to rotate in plane of field,(Where U is potential energy and tau is torque)

A short bar magnet of magnetic moment m=0.32 JT^(-1) is placed in a uniform magnetic field of 0.15 T. If the bar is free to rotate in the place of the field , which orientation would correspond to its (a) stable , and (b) unstable equilibrium ? What is the potential energy of the magnet in each case ?
