Why is soft iron used as the core of the electromagnet in an electric bell ?

Pieces of soft iron used for the storage of magnets

The purpose of armature in an electric bell is :

An electromagnet is made using

An electromagnet is used in :

Soft iron is used for making electromagnet because it

Fig. shows a coil wound around a soft iron bar XY. Suggest one way of increasing the strength of the electromagnet so formed.

Why is the core of a transformer laminated?

In an electric bell, when the metal strip gets attached to the electromagnet , it no longer touches the interrupter , and hence the circuit breaks.

The magnetic induction and the intensity of magnetic field inside an iron core of an electromagnet are 1 Wbm^(-2) and 150Am^(-1) respectively. The relative permeability of iron is : (mu_(0)=4pixx10^(-7)"henry"//m)
