A technician wraps wire around a tube of length 44 cm having a diameter of 7.0 cm. When the windings are evenly spread over the full length of the tube, the result is a solenoid containing 730 turns of wire. (b) If the current in this solenoid increases at the rate of +2.5 A/s, what is the self-induced emf in the solenoid?

Expert Solution
Step 1
dia of tube = 7cm
length of wire = 44cm
therefore the number of turn N =730
self-inductance of coil L= henry
