Test Preparation on Electromagnetic Induction-I-Physics Test Series IIT JEE-2020

A copper ring is held horizontally and a bar magnet is
dropped through the ring with its length along the axis of the
ring. The acceleration of the falling magnet while it is
passing through the ring is

A rectangular, a square, a circular and an elliptical loop, all
in the (x - y) plane, are moving out of a uniform magnetic
field with a constant velocity V = v ˆi
r
. The magnetic field is
directed along the negative z-axis direction. The induced
emf, during the passage of these loops, out of the field
region, will not remain constant for
