Question
A flat coil of wire, consisting of 20 circular loops, with a total resistance of 20.0 ohms, is placed so that it is at rest, flat on a table. The graphs above show the magnetic flux through each loop of the coil as a function of time, for three different cases. The units of flux are webers, which are equivalent to tesla meters2. The flux through each loop changes because the magnetic field changes . Assume that the field is uniform and the direction of the field is perpendicular to the plane of the coil - positive flux means the field is passing in one direction through the coil, and negative flux means that the field is passing through the coil in the opposite direction.
(a) In which case is the magnitude of the induced current larger at t = 3 s?
(b) Consider case A only. At t = 8 s, the induced current is directed clockwise. At which other times, for case A, is the induced current also directed clockwise. Select all that apply?
