a. What is the magnetic flux through one turn of a solenoid of self inductance `8.0xx10^-5H` when a current of `3.0 A` flows throgh it? Assume that the solemoid has 1000 turns ans is wound from wire of diameter `1.0 mm`.
b. What is the cross sectional area of the solenoid?

The magnetic field at a point on the axis of a long solenoid having 5 turns per cm length when a current of 0.8 A flows through it is

An air core solenoid has 1000 turns and is one metre long. Its cross-sectional area is 10cm^(2) . Its self-inductance is

A 0.5 m long solenoid has 500 turns and has a flux density of 2.52 xx 10^(-3) T at its centre. Find the current in the solenoid.

An iron core is inserted into a solenoid 0.5 m long with 400 turns per unit length. The area of cross-section of the solenoid is 0.001m^(2) . (a) Find the relative permeability of the core when a current of 5 A flows through the solenoid winding. Under these conditions, the magnetic flux through the cross-section of the solenoid is 1.6xx10^(-3) Wb. (b) Find the inductance of the solenoid under these conditions.
