A technician wraps wire around a tube of length 37.0 cm having a diameter of 7.70 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 inductance of this solenoid.
(b) If the current in this solenoid increases at the rate of 6.00 A/s, find the self-induced emf in the solenoid?
