Hard ferrite condition forced more than Soft ferrite and is therefore suitable for use as a magnet. On the contrary, Soft ferrite is often used to prevent noise or using a magnetic head.
Hard ferrite with more force, so it is suitable for Soft ferrite magnets. In contrast, Soft ferrite is often used to prevent noise or primarily used as a magnetic head.
