Why is the core of a transformer made of soft iron?

The soft iron core increases the strength of the magnetic field inside a transformer. The main purpose of using an iron core in a transformer because iron is a magnetic material and it is easily available everywhere. The core is laminated to reduce the Eddy current and hence Eddy current losses.

Consequently, which material used in transformer?

In alternating current (AC) devices they cause energy losses, called core losses, due to hysteresis and eddy currents in applications such as transformers and inductors. "Soft" magnetic materials with low coercivity and hysteresis, such as silicon steel, or ferrite, are usually used in cores.

What is the core of a transformer made of?

In all types of transformer construction, the central iron core is constructed from of a highly permeable material made from thin silicon steel laminations assembled together to provide the required magnetic path with the minimum of losses.

What material is used for the core of an electromagnet?

A simple electromagnet consisting of a coil of wire wrapped around an iron core. A core of ferromagnetic material like iron serves to increase the magnetic field created. The strength of magnetic field generated is proportional to the amount of current through the winding.
