Explanation:

Answer 2

Answer:-

The simplest motion producer is a solenoid, which consists of a coil with a soft iron core (or armature) which slips easily in and out of the coil. Soft iron is used because it does not retain its magnetism when the current is switched off; in other words, it does not become permanently magnetized

Soft iron is used in magnetic assemblies, electromagnets and in some electric motors; and it can create a concentrated field that has more intense than an air core. Soft iron that has a low carbon content and is easily magnetized and demagnetized, used to make the cores and other electrical equipment.
