A 37-turn circular loop of wire is placed into a magnetic fieldwith initial magnitude 4.9 T. The magnetic field is perpendicularto the surface of the loop. Over a period of 0.45 seconds, thestrength of the field is decreased to 2.1 T and as the fielddecreases a 4.5 V emf is induced in the loop. Calculatethe diameter of the loop of wire
