The current is flowing through solenoid, then solenoid acting as what ?

The current flowing through the zener diode in fig is-

Current I is following through a toroidal solenoid of radius r, length l and area A. If the number of turns of toroidal solenoid is N, then energy stored in the toroidal solenoid is …..

A (current vs time) graph of the current passing through a solenoid is shown in figure. For which time is the back electromotive force ( epsilon ) a maximum. If the back emf at t = 3s is e, find the back emf at 1 = 7 s, 15 s and 40 s. OA, AB and BC are straight line segments.

What is value of current flowing through galvanometer in balanced condition of Wheatstone bridge ?

What is solenoid ?

What is long solenoid ?

A closely wound solenoid of 800 turns and area of cross section 2.5 times 10^-4 m^2 carries a current of 3.0A. Explain the sense in which the solenoid acts like a bar magnet.

Series combination of 10 Omega resistance and 5 cm long solenoid having 5 mH self inductance are connected to 10 V battery. Current passing through solenoid in steady state is ___

A closely wound solenoid of 800 turns and area of cross section 25 xx 10^(-4)m^(2) carries a current of 3.0 A. Explain the sense in which the solenoid acts like a bar magnet. What is its associated magnetic moment?
