Concept

Problem: Consider a coil composed of ten loops of wire. Each loop has an area of 0.23. The coil has a very large resistance and is placed in a 0.047 tesla uniform magnetic field, oriented so that the maximum flux goes through the coil. The coil is then rotated so that the flux through it goes to zero in 0.34 s. What is the magnitude of the average voltage induced in the coil over this time interval? A) 0.00 V B) 1.0 V C) 0.0032 V D) 0.32 V E) 0.032 V
