A technician wraps wire about a tube of length 33.0 cm having a diameter of 7.70 cm. If the windings are equally spread over the full length of the tube, the outcome is a solenoid having 550 turns of wire.
i) Determine the inductance (in mH)
ii) When the current in the solenoid rises at the rate of 3.00 A/s, determine the self-induced emf in the solenoid?
