State qualitatively the effect of inserting an iron core into a current-carrying solenoid.

What is the effect of inserting a soft iron core inside a current-carrying solenoid?

In case of a current carrying solenoid

(a) What is a solenoid ? Draw a sketch to show the magnetic field pattern produced by a current-carrying solenoid. (b) Name the type of magnet with which the magnetic field pattern of a current-carrying solenoid resembles. (c ) What is the shape of field lines inside current-carrying solenoid ? What does the pattern of field lines inside a current-carrying solenoid indicate ? (d) List three ways in which the magnetic field strength of a current-carrying solenoid can be increased ? (e) What type of core should be put inside a current-carrying solenoid to make an electromagnet ?

A solenoid carrying a current supplied by a DC source with a constant emf contains an iron core inside it. How will the current change when the core is pulled out of the solenoid: will it increase, decrease, or remain the same?

There is one tightly wound long solenoid carrying current 2 A. Solenoid have 100 turns per cm. H_1 is the magnetic intensity and B_1 is the magnetic field at the centre of solenoid. Now an iron core is inserted inside the solenoid. Intensity of magnetization in the core is 4 xx 10^6 A/m. New values of magnetic intensity and magnetic field at the centre becomes H_2 and B_2 Value of H_2//H_1 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) ?
