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.

The magnets with countersunk holes are generally mainly neodymium magnets, mainly because the neodymium material is easy to process and the magnetic force is satisfied. Such ferrite rectangular magnets with (punched) countersunk holes are rare, mainly requiring molds. , If you are interested in this product, you can contact the website customer service or leave a message online....
You are now seeing the specifications of this magnet ring OD 13mm, bore diameter 8mm, thickness of 3.5mm, the surface of the black epoxy, due to the reason of the photo may look like a ferrite, the actual bonded ring magnets, suitable for a variety of types of motor, sensor, and electric appliances....
Neodymium iron boron is divided into sintering, bonding and injection molding according to the different production processes. The general neodymium arc magnet is sintered, also called sintered arc neodymium magnet. Today this product is a bonded arc magnet that is not much used. The difference between sintered arc magnets is that bonded NdFeB magnet tiles require molds to produce....
