Powe r Generation. The diagram shows a flexible loop of wire between the poles of an electromagnet which provides a uniform field B in the region of the loop. At time t = 0, the current through the electromagnet is turned off, and the field B then falls to zero at time t1 as shown.

The diagram shows a flexible loop of wire between the poles of an electromagnet which provides a uniform field B in the region of the loop. At time t = 0, the current through the electromagnet is turned off, and the field B then falls to zero at time t1 as shown. Draw a diagram to represent the EMF across the ends of the loop as a function of time.
