About Neodymium Magnets

Why should I be so careful with neodymium magnets?

They are surprisingly strong, much more powerful than most other magnets you may have handled. When you are separating and working with them, they will jump back together unexpectedly. In fact, the greater force exerted by rare earth magnets creates hazards that are not seen with other types of ceramic or alnico magnets. Neodymium magnets that are larger than a few centimeters are strong enough to cause injuries including pinched and/or lacerated fingers. Strong magnets can even cause broken bones. So be careful. Magnets that are allowed to get too near to each other can suddenly jump together and strike...

What are the most common applications of neodymium magnets?

The most common places you’ll find neodymium magnets include: Retail signs and counter displays. Trade show booths and staging structures. Leather purses, bags, garments and holsters. Custom boxes for premium products. Presentation folders and scrapbooks. Arts, crafts and jewelry. Wood doors and cabinets as door latches. Health bracelets, bandages and other medical devices. Window coverings and blinds. Magnetic resonance imaging (MRI) devices. Audio speakers. Vacuum cleaners and other motorized household appliances. Bicycle dynamos. Computer hard drives. Wind turbine generators. Fishing reel brakes. Permanent magnet motors in cordless tools. High-performance AC servo motors. Traction motors. Integrated starter-generators in hybrid and electric...

Why are most neodymium magnets plated or coated?

Neodymium magnets are composed mainly of neodymium, iron and boron. If they are not plated, the iron in the material will oxidize very easily, particularly if exposed to moisture. Even normal humidity will rust any iron anywhere over time. That’s why, in order to preserve and protect the lasting performance of each magnet’s magnetic field, most neodymium magnets are plated or coated. Nickel is the most common choice, as it is durable and cost-effective. Our magnets are coated with a triple plating of nickel-copper-nickel. This creates a shiny silver finish and provides dependable resistance to corrosion in most applications.

What does the "N rating" on neodymium magnets mean?

The magnet grade or "N rating" refers to the Maximum Energy Product of the material that the magnet is made from; and it refers to the maximum strength that the material can be magnetized to permanently hold. Generally speaking, magnets range from N35 to N52 in grade. The higher the grade number, the incrementally stronger the magnet will be. The grades of neodymium magnets that we normally carry are N42 and N52, a rating that is generally measured in Tesla metrics or units of Gauss Oersted (MGOe). A magnet of grade N42 has a Maximum Energy Product of Gauss 42 MGOe,...

Why are neodymium magnets considered to be the strongest magnets on earth?

Developed by physicists during the 1970s, neodymium magnets are considered to be the strongest permanent magnets in existence. This is because they create the highest magnetic field per size and volume of any other known natural or man-made material. The magnetic field typically produced by rare earth neodymium magnets can be in excess of one-point-four (1.4) Teslas, whereas all other magnets normally generate fields of zero-point-five (0.5) to one (1) Tesla. And not only are neodymium magnets the most powerful magnets on the planet, they are also the most affordable type of rare earth magnet available today.
