Magnetic Dipole In Uniform Magnetic Field

The torque and magnetic potential energy of a magnetic dipole in most stable position ina uniform magnetic field vec(B) having magnetic moment vec(m) will be

With a standard rectangular bar magnet, the time period in the uniform magnetic field is 4 sec . The bar magnet is cut parallel to its length into 4 equal pieces. The time period in the uniform magnetic field when the piece is used (in sec) (bar magnet breadth is small)

Magnetic dipole moment vecM of the coil, placed in uniform magnetic field of induction vecB does not depend on
