A magnetic dipole is placed in a uniform magnetic fields, B, when the potential energy is minimum

What is magnetic field?

A short bar magnet of magnetic moment 0.4JT^-1 is placed in a uniform magnetic field of 0.16 T. The magnet is in stable equilibrium when the potential energy is

Show that the magnetic flux through a surface of area A placed in a uniform magnetic field B is defined as phi_B = BA cos theta where theta is the angle between vec A and vec B .

A rectangular coil carrying current is placed in a uniform magnetic field in such a way that normal to the coil makes an angle theta with the direction of magnetic flux density. Find the magnitude of torque acting on the coil Define magnetic moment of a current loop.

A metal rod of length l is placed normal to a uniform magnetic field B. The rod moves with velocity v perpendicular to the field. Show that motional emf across its ends is Blv.
