A 15-turn circular loop of wire is placed into a magnetic fieldwith initial magnitude 3.9 T. The magnetic field is perpendicularto the surface of the loop. Over a period of 0.35 seconds, thestrength of the field is decreased to 1.3 T and as the fielddecreases a 3.5 V emf is induced in the loop. Calculate thediameter of the loop of wire.
