1. A 15-turn circular loop of wire is placed into a magneticfield with initial magnitude 3.9 T. The magnetic field isperpendicular to the surface of the loop. Over a period of 0.35seconds, the strength of the field is decreased to 1.3 T and as thefield decreases a 3.5 V emf is induced in the loop. Calculate thediameter of the loop of wire.
