Magnetic Shielding of silicon steel

What is silicon steel and its magnetic properties?

Silicon steel, also known as electrical steel, is a special type of steel that is tailored to have specific magnetic properties. It is used in the cores of electrical transformers, motors, and inductors due to its high magnetic permeability and low core loss.

The addition of silicon to steel increases its resistivity, which reduces eddy current losses. Eddy currents are circular electric currents induced within conductors by a changing magnetic field, and they can cause significant energy losses in electrical devices.

The magnetic properties of silicon steel are characterized by its high magnetic permeability and low coercivity. Magnetic permeability is a measure of how easily a material can be magnetized, and silicon steel has a high permeability, which means it can be easily magnetized. Coercivity is a measure of a material’s resistance to becoming demagnetized, and silicon steel has a low coercivity, which means it is easy to demagnetize.

These properties make silicon steel an ideal material for use in electrical devices, where it can be easily magnetized and demagnetized without significant energy losses.

How does magnetic shielding work in silicon steel?

The intricate dance of magnetic shielding in silicon steel involves the art of diverting magnetic field lines away from delicate components or regions of interest. This feat is accomplished by encircling the desired area with a substance possessing high magnetic permeability, such as the renowned mu-metal or permalloy. The magnetic shielding material adeptly absorbs and redirects the magnetic flux, thereby diminishing the intensity of the magnetic field within the shielded confines.
