An electron revolves in a circular orbit of radius r with uniform angular speed omega . From the expression for magnetic field due to current carrying circular conductor, deduce the expression for magnetic field at the center of electron orbit.

A charged partice is moving in a circle of radius R with uniform speed v. The associated magnetic moment mu is given by

A uniform magnetic field acts right angles to the direction of motion of electrones. As a result, the electron moves in acircular path of radius 2 cm. If the speed of electrons is doubled, then the radius of the circular path will be
