The magnetic induction at the centre of a solenoid is B . If the length of the solenoid is reduced to half and the same wire is would in two layers the new magnetic induction is

The magnetic induction at the centre of a solenoid is B . If the length of the solenoid is reduced to half and the same wire is would in two layers the new magnetic induction is

The magnetic induction due to toroidal solenoid is independent of

At the mid point along the length of a long solenoid, the magnetic field is equal to x . If the length of the solenoid is doubled and the current is reduced to half, the field at the new mid point will be nearest to

How does magnetic induction inside a solenoid change due to a change in number of turns of the solenoid?

A solenoid have self inductance 2H. If length of the solenoid is double having turn density and area constant then new self inductance is :-

A solenoid have self inductance 2H. If length of the solenoid is double having turn density and area constant then new self inductance is :-

A tightly-wound, long solenoid having 50 turns cm^(-1) , carris a current of 4.00 A . Find the magnetic intensity H and the magnetic field B at the centre of the solenoid. What will be the values of these quantities if an iron core is inserted in the solenoid and the magnetization I in the core is 4.00 xx 10^6 A m^(-1) ?
