Homework Statement
An elastic conducting material is stretched into a circular loop of 20.0 cm radius. It is placed with its plane perpendicular to a uniform 0.900 T magnetic field. When released, the radius of the loop starts to shrink at an instantaneous rate of 78.0 cm/s. What emf is induced in the loop at that instant?
