A point charge is moving in clockwise direction in a circle with constant speed. Consider the magnetic filed produced by the charge at a fixed point P ( not at the centre of circle ) on the axis of the circle. Then,

A conducting current-carrying plane is placed in an external uniform magnetic field. As a result the magnetic induction becomes equal to B1 on one side of the plane and B2 on the other side. Find the magnetic force acting per unit area of the plane.
