Soft iron is used in making the armature of an electric bell because it
Answer Details
Soft iron is used in making the armature of an electric bell because it loses its magnetism readily. This is due to its low coercivity, which means that it is easily magnetized and demagnetized. In an electric bell, the armature needs to be magnetized and demagnetized rapidly in order to vibrate back and forth, striking the bell and producing the sound. If the armature were made of a material that retained its magnetism for a long time, it would not vibrate back and forth as required, and the bell would not ring properly. Therefore, soft iron is an ideal material for the armature of an electric bell because it can be easily magnetized and demagnetized, allowing the bell to ring properly.
