A guitar's steel string vibrates (see figure below). The component of magnetic field perpendicular to the area of a pickup coil nearby is given by
B = 50.0 + 3.20 sin 1 046????t
where B is in milliteslas and t is in seconds. The circular pickup coil has 29 turns and radius 2.55 mm. Find the emf induced in the coil as a function of time. (Use the following as necessary: t. Let ???? be measured in millivolts with t measured in seconds.)
