The core of a relay is typically made of soft iron because it has high magnetic permeability, which allows it to create a strong magnetic field when a current passes through the coil. This strong magnetic field helps to attract and hold the movable armature in place, enabling the relay to switch electrical circuits on and off effectively.
The strength of the magnetic field increases when inserting a soft iron core into a solenoid because the soft iron core is easily magnetized by the current flowing through the solenoid. This creates alignment of the magnetic domains in the soft iron core, enhancing the magnetic field strength within the core and around the solenoid. Soft iron has high magnetic permeability, which concentrates the magnetic field lines and increases the overall magnetic field strength.
Electromagnets are produced by running electric current through a soft iron core. Soft iron enhances the magnetic properties and creates a temporary magnetism as long as the current flows through the core.
A soft iron core can function as a switch in an electromagnet system by being magnetized when a current is applied, allowing the electrical circuit to be completed and turning on the switch. When the current is turned off, the soft iron core loses its magnetization, breaking the circuit and turning off the switch.
A relay is made up of a coil with an iron core and a movable iron bar. The movable iron bar in a relay is called a switch.
Yes, wrapping a wire around a soft iron core in an electromagnet increases the concentration of the magnetic field produced. This is due to the high magnetic permeability of the soft iron core which helps to focus and amplify the magnetic field generated by the current in the wire.
because it can magnetize and demagnetize easily

It has been found that if a soft iron rod called core is placed inside a solenoid, then the strength of the magnetic field becomes very large because the iron core is magnetized by induction The core of the electromagnet must be of soft iron because soft iron loses all of its magnetism when current in the coil is switched off or stopped

No, the core has to be a soft iron core.

Soft iron has a greater permeability than steel. BTW, the only reason for laminations is to reduce eddy currents in the core. It has no effect on permeability or inductance.
