A technician wraps wire around a tube of length 37 cm having a diameter of 8.3 cm. When the windings are evenly spread over the full length of the tube, the result is a solenoid containing 565 turns of wire.
(a) Find the self-inductance of this solenoid.
mH
(b) If the current in this solenoid increases at the rate of 2 A/s, what is the self-induced emf in the solenoid?
mV
