Watch out a lot more about it. Then, why iron is chosen as the material for the core of the transformer?
It is used for transformer core because it is near to a ferro-magnetic material. The advantage of using a ferro-magnetic material above a usual material like iron or aluminium is that their permeability is high i.e. they allow the magnetic flux to pass through them at a higher rate than other material.
Subsequently, question is, which material is used for the core of a transformer and why? In all types of transformer construction, the central iron core is constructed from of a highly permeable material made from thin silicon steel laminations. These thin laminations are assembled together to provide the required magnetic path with the minimum of magnetic losses.
In respect to this, why is ferromagnetic material used in a power transformer core?
It is made of ferromagnetic metal such as iron, or ferrimagnetic compounds such as ferrites. The high permeability, relative to the surrounding air, causes the magnetic field lines to be concentrated in the core material. The magnetic field is often created by a current-carrying coil of wire around the core.
What is the best material for the core of a transformer?
Soft iron
