A copper hoop is held in a vertical east-west plane in a uniform magnetic field whose field lines run along the north-south direction. The largest induced emf is produced when the hoop is
rotated about a north-south axis
rotated about an east-west axis
moved rapidly, without rotation, toward the east
moved rapidly, without rotation, towards the south
moved rapidly, without rotation, towards the northwest
all the above
The diagram above shows an inductor that is part of a circuit. The direction of the emf induced in the inductor is indicated. Which of the following is possible?
The current is constant and rightward
the current is constant and leftward
the current is increasing and rightward
the current is increasing and leftward
An 8.0 mH inductor and a 2.0 Ohm resistor are wired in series to an ideal battery. A switch in the circuit is closed at time 0, at which time the current is zero. The current reaches half its final value at time:
