Acoil is wrapped with 300 turns of wire on the perimeter of a circular frame (radius = 8.0 cm). each turn has the same area, equal to that of the frame. a uniform magnetic field is turned on perpendicular to the plane of the coil. this field changes at a constant rate from 20 to 80 mt in a time of 20 ms. what is the magnitude of the induced emf in the coil at the instant the magnetic field has a magnitude of 50 mt?

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
