The armature of a small generator consists of a flat, square coil with 180 turns and sides with a length of 1.40 {\rm cm}. The coil rotates in a magnetic field of 8.75×10−2 {\rm T}.
What is the angular speed of the coil if the maximum emf produced is 2.60×10−2 {\rm V}?

A closely wound search coil has an area of 3.15 {\rm cm^2}, 110 turns, and a resistance of 61.4 \Omega. It is connected to a charge-measuring instrument whose resistance is 46.9 {\rm \Omega}. When the coil is rotated quickly from a position parallel to a uniform magnetic field to one perpendicular to the field, the instrument indicates a charge of 3.46×10−5 {\rm C}.
What is the magnitude B of the field?
