Note:
The equation implies that since are always perpendicular, the magnetic force does no work. [This means the force cannot change the speed of the particle]. In such a case the kinetic energy remains constant. The work-energy theorem implies that work is said to be done by a force if it brings abou..

Torque on a Bar Magnet in a Uniform Magnetic Field
The behavior of a bar magnet in a uniform magnetic field is similar to that of electric dipole in a uniform electric field. The above figure. Let 2l be the magnetic length of a magnet and m be the strength of each pole. These two forces, being equal and opposite having different lines of ..
