    Soft Magnetic Alloy:

    The use of soft magnetic alloys is very extensive. Because they are easy to magnetize and demagnetize, and have a high magnetic permeability, they can play a good role in gathering magnetic lines of force. Therefore, soft magnetic alloys are widely used as magnetic flux paths, ie, as magnetically conductive materials such as transformers and sensors. Cores, magnetic shields, yokes for special magnetic circuits, relays, transformers, magnetic amplifiers, electromagnetic clutches, automotive sensors, etc.
