B along the axis of a solenoid is given by :-

The correct curve between the magnetic induction (B) along the axis of a along solenoid due to current flow i in it and distance x from one end is -

A horizontal solenoid is connected to a cell and a switch, Fig. A Copper ring with its axis along the axis of the solenoid is placed on a frictionless track. What happen to the ring, as the switch is closed ?

A metal rod is placed along the axis of a solenoid carrying a high-frequency alternating current. It is found that the rod gets heated. Explain why the rod gets heated .

A slightly divergent beam of charged particles accelerated by a Potential difference V propogates from a point A along the axis of a solenoid. The beam is brought into focus at a distance l from the point A at two successive values of magnetic induction B_1 and B_2. Find the specific charge q//m of the particles.

The magnetic field along the axis of an air cored solenoid is B. The magnetic field energy density is

shows a horizontal solenoid connected to a battery and a switch. A coper ring is placed on a frictionless track, the axis of the ring being along the axis of the solenoid. As the switch is closed, the ring will

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.

A short solenoid of length 4 cm, radius 2 cm and 100 turns is placed inside and on the axis of a long solenoid of length 80 cm and 1500 turns. A current of 3 A flows through the short solenoid. The mutual inductance of two solenoid is

A solenoid 60 cm long and of radius 4 cm has 3 layer of windings 300 turns each. A 2.3 cm long wire of mass 2.5g lies inside the solenoide near its center normal to its axis, both the wire and the axis of the solenoid are in the horizontal plane. The wire is connected through two leads parallel to the axis of the solenoid to an external battery which supplies a current of 6A in the wire. What value of current (with appropriate sense of circulation) in the windings of the solenoid can support the weight of the wire?
