What are soft ferromagnetic materials? Write the uses of soft ferromagnetic materials.

(N/A) Soft ferromagnetic materials are magnetic materials that can be easily magnetized and demagnetized.
They possess low retentivity,low coercivity,and low hysteresis loss.
Due to these properties,they are ideal for applications where rapid changes in magnetic fields occur.
Uses of soft ferromagnetic materials:
$1$. They are used in the cores of transformers and electromagnets.
$2$. They are used in the cores of inductors and chokes.
$3$. They are used in telephone diaphragms and magnetic shielding.
