A current carrying ring is placed in a horizontal plane. A charged particle is dropped along the axis of the ring to fall under the influence of gravity

A bar magnet is dropped along the axis of copper ring held horizontally. The acceleration of fall is

A bar magnet is dropped along the axis of copper ring held horizontally. The acceleration of fall is

A circular ring of mass M and radius 'a' is placed in a gravity free space. A small particle of mass m placed on the axis of the ring at a distance sqrt(3)a from the center of the ring, is released from rest. The velocity with which the particle passes through the center of the ring is

A current-carrying ring is placed in a magnetic field. The direction of the field is perpendicular to the plane of the ring (i) There is no net force on the ring (ii) The ring will tend to expand (iii) The ring will tend to contract (iv) Either (ii) or (iii) depending on the directions of the current in the ring and the magnetic field

A copper ring is held horizontally and a bar magnetic is dropped through the ring with its length along the axis of the ring (shown in the figure) will the acceleration of the falling magnet be equal to , greater than or less than that due to gravity?

A coil A of radius R and number of turns n carries a current i and it is placed in a horizontal plane. A small conducting ring P of radius r (r lt lt R) is placed at a height y_(0) above the centre of the coil A as shown in figure-5.38. Calculate the induced EMF in the ring when the ring in allowed to fall freely. Express the induced EMF as a function of instantaneous speed of the falling ring and its height above the center of the coil A.
