Problem
A rectangular conducting loop with width 0.10m and length 0.40m is pulled at a constant speed of 2.0m/s from a region of uniform magnetic field 0.50T that is directed into the page. The loop is oriented so that its plane is perpendicular to the field, and it is pulled out perpendicular to its width so that the width exits first. While part of the loop is still within the field region, what is the magnitude of the induced emf?
(a) 0.050V
(b) 0.20V
(c) 0.10V
(d) 0.12V
