Magnetic induction is the process by which a magnetic field induces a voltage in a conductor. In soft iron, magnetic induction occurs more easily than in steel because of its higher permeability. This means that when a magnetic field is applied to soft iron, it will induce more voltage than if the same field were applied to steel. The higher permeability of soft iron is due to the fact that it has a lower coercive field strength than steel, meaning that its domains are more easily aligned with an external magnetic field.
