Why soft magnetic material is used in transformer?

Best Answers

Transformer core requires magnetization, demagnetization and reverse magnetization during operation. The energy expended in doing so in the form of hysteresis losses should be minimum. This corresponds to low coercive force on the magnetization curve of the material and small area of hysteresis loop. See the figure. read more

This is why magnetic materials are used in transformers and motors as it has been found they can produce extremely high magnetic flux densities, which we may exploit. In a sense the soft iron core acts like a"magnetic field amplifier" and where the term magnetic amplifier arose. The core allows a great saving in copper to be achieved. read more

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. read more
