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 …..

Toroid is a solenoid of

Solenoid || Toroid

The magnetic induction due to toroidal solenoid is independent of

Solenoid and Toroid

A solenoid of radius R and length L has a current I = I​_0 cosωt. The value of induced electric field at a distance of r outside the solenoid, is

The self inductance L of a solenoid of length l and area of cross-section A, with a fixed number of turns N increases as

Current I flows through solenoid of length L having N number of turns, when it is connected to DC emf. If charged particle is projected along the axis of solenoid with a speed v_(0) , them find the force on the charged particle in the solenoid.
