Just now, I saw an interesting topic of magnets. Some people asked if the magnets are waterproof? Some said they were waterproof, and some said they were not waterproof. Let me share with you below.
Are Rare Earth (NDFEB) Magnets Waterproof?
The picture shows NdFeB strong magnetic waterproof encapsulated magnet
Normally neodymium strong magnets are not waterproof, although magnets are usually coated with a protective layer such as nickel copper nickel, zinc or epoxy to prevent rust and moisture corrosion, they are not waterproof, neodymium magnets can get wet or submerged for a short period of time , especially in the case of poor coating treatment.
Are ceramic ferrite magnets waterproof?
The ferrite magnets waterproof is no problem and can work underwater for a long time.
Nowadays, some customers still want neodymium magnet material, and the magnet manufacturers use the method of encapsulation (wrapping iron iron boron) or compress the high frequency of the magnet with PVC to isolate the magnet from air and water for waterproof purposes.
