Neodymium(Rare Earth) Ring Magnets

Neodymium(NdFeB) ring magnets are also known as rare earth ring magnet. They have a flat design,which is similar to disc magnet, but with a hole in the middle. Because there is a hole in the center of the round magnet, they have greater versatility.The center hole, which allow them to be recessed and screwed into place, are commonly used in joinery and workshop accessories. Ring shaped neodymium magnet is one of the most popular shapes of rare earth neodymium magnets. Meank magnetics provides the highest quality strong rare earth neodymium(NdFeB) magnet rings. We have a wide range of neodymium ring magnet for sale, including different grade, and several different coatings and different sizes. Different coatings commonly used include nickel, zinc, epoxy or gold to protect magnetic materials and reduce corrosion.

Types of Neodymium Ring Magnets

Neodymium Ring Magnets Features & Characteristics

  • Neodymium Ring magnets are the strongest commercially produced rare earth ring magnets.

  • Rare earth neodymium ring magnets are hard and brittle and may chip or break if dropped.

  • Neodymium magnets rings are usually magnetized through the thickness.

  • Uncoated neodymium ring magnets are not rustproof and may corrode in humid conditions.

  • Operating temperatures of neodymium ring magnets vary among material grades. 

  • Neodymium ring magnets can be assembled by using strong adhesives. Make sure that all contact surfaces are clean and dry prior to bonding.

Neodymium Ring Magnet Applications

Because of its high permeability, neodymium ring magnets are the best solution for a range of magnetic applications. Our strong neodymium ring magnets are widely used for magnetic fishing. Our strong rare earth(neodymium)ring magnets are also widely used in scientific projects or experiments, medical applications, package,cabinets, water conditioning, speakers, etc.

FAQS About Neodymium Ring Magnets

  • How neodymium ring magnets made out?

    Simply speak,neodymium ring magnets are made out by steps of sintering,drilling and cutting.Surface treatment is needed for neodymium ring magnets,because they are not corrosion resistant.

  • What’s the strongest & most powerful ring magnet on the world?

    Rare earth ring magnets are usually known as strong type ring magnet,and strongest and most powerful ring magnet for the same size must be made of rare earth neodymium.

  • How to express a ring shape neodymium magnet?

    Like as other ring magnet, a ring shaped neodymium magnets are expressed with out-diameter,inner diameter and thickness, for example: OD x ID x H(T)
