A rectangular, a square, a circular and an elliptical loop, all in the 
plane, are moving out of a uniform magnetic field with a constant velocity, 
. The magnetic field is directed along the negative 
axis direction. The induced 
during the passage of these loops, out of the field region, will not remain constant for
Text Solution
Verified by ExpertsThe correct answer is:
A
Once a rectangular loop or a square loop is being drawn out of the field, the rate of cutting the lines of field will be a constant for a square and rectangle, but not for circular or elliptical areas.
