Permanent Hard Ferrite magnet is made of SrO or BaO and Fe2o3 by ceramic processing. And ferrite disc magnets are round coin-shaped ceramic ferrite magnets of varying diameter and thickness. The ferrite disc magnets are almost always manufactured as axially magnetised ceramic ferrite magnets.
Hard ferrite magnets have excellent electrical isolation effects and ar exhausting to demagnetize even in robust external magnetic fields. Corrosion tendency is low, creating them terribly appropriate for liquid applications. The magnets are widely used in loudspeaker, motor, toys, medical apparatus, ect.
