A solenoid has `10^(3)` turns per unit length. On passing a current of 2A, magnetic induction is measured to be `4 pi (Wb) / (m)^(2)`. Calculate the magnetic susceptibility of the core.

A long solenoid has 200 turns per cm and carries a current of 2.5A. The magnetic field at its centre is

The magnetic field (B) inside a long solenoid having n turns per unit length and carrying current / when iron core is kept in it is (mu_o = permeability of vacuum, chi = magnetic susceptibility)

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

A long solenoid has 800 turns per metre length of solenoid A current of 1.6 A flow through it. The magnetic induction at the end of the solenoid on its axis is

There is one current carrying solenoid with 750 turns per metre. A current of 2 A is flowing through the solenoid. A rod of certain material is inserted as core inside this solenoid and the intensity of magnetization is found to be 0.12 A/m. What is magnetic susceptibility of the material used? What kind of material is this?

A long solenoid with 40 turns per cm carries a current of 1 A. The magnetic energy stored per unit volume is..... J m^(-3) .
