A technician wraps wire around a tube of length 33 cm having a diameter of 7.9 cm. When the windings are evenly spread over thefull length of the tube, the result is a solenoid containing 570 turns of wire.
(a) Find the self-inductance of this solenoid.
mH
(b) If the current in this solenoid increases at the rate of 5 A/s, what is the self-induced emf in thesolenoid?
mV
