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 [...]
