A small circular loop of radius 10−3 m has its plane parallel to the wire and is placed at a distance of 1 m from the wire. The resistance of loop is 5 pie ×10^−4(Ω). Find the approximate value of induced current in the loop.

A bar magnet is released from rest and starts falling through a metal ring as shown in fig A wire loop is suspended from a string that is attached to point P in the drawing. When released but in case (II) it has been cut through. discuss the motion of the magnet in both cases when it is above the ring and below the ring as well. consider ywo cases from left to right in case (I) the ring is solid all the way around the loop swings downward through a uniform magnetic field
