The current in a solenoid of 240 turns, having a length of 12 cm and a radius of 2 cm, changes at a rate of 0.8 A s^(-) . Find the emf induced in it.

The current is a solenoid of 240 turns, having a length of 12 cm and a radius of 2 cm, changes at a rate of 0.8 A s^(-) . Find the emf indcued in it.

A solenoid having 500 turns and length 2 m has radius of 2 cm , the self inductance of solenoid

A technician wraps wire around a tube of length 4pi^2 cm having a diameter of 8.00cm. When the windings are evenly spread over the full length of the tube, the result is a solenoid containing 1000turns of wire. If the current in this solonoid increases at the rate of 4.00A/s the self-induced emf in the solenoid is
