Everything You Should Know About N42 Neodymium Magnets

Grade N42 neodymium magnets are the ideal DIY Parts & Options. They can be used as a magnet rotor, closure, mount, linear coupler, connector, Halbach Array, holder, stand, etc., helping you with the development of new inventions and making your life easier. Therefore, you can find permanent magnets on many amazing novel products in Stanford Magnets. Most of our customers directly pointed out that they needed an N42 rare earth magnet at their first magnet inquiry.

What does grade n42 magnet mean?

The grade N42 means a neodymium magnet has a maximum energy product of 42 MGOe. It refers to the maximum magnetic energy that the material can be stored. It can be shown by the magnet's Demagnetization Curve, or BH Curve - the strongest point is (BH)max. Generally speaking, the higher the grade, the stronger the magnet. Currently, the highest grade of neodymium magnet available is N55, and the lowest is N35.

What do grades N42M, N42H, N42SH, and N42UH mean?

Compared with N42, N42M, N42H, N42SH, and N42UH come with different letters. These grades' following letters refer to the temperature rating of the sintered neodymium rare earth magnet. N42M is 100℃, N42H is 120℃, N42SH is 150℃ and N42UH is 180℃. Therefore, N42SH high working temperature neodymium magnets are widely used on a motor. You can find our specifications of N42 series Neodymium Magnets as below or for the full grade table, please visit Sintered Neodymium Magnet Characteristic.

Shapes of N42 Super Strong Neodymium Magnets

There are many shapes of N42 neodymium magnets such as arc, ring, block, disc, and so on.

Why do so many customers choose N42 neodymium rare earth magnets?

Due to N42 neodymium magnets for sale is a great balance among cost, strength, and performance under 80℃ operating temperatures. Although there are higher grades, such as N52 and N52, the max working temperature is only 60℃. And not only the higher the grade, the stronger the magnet, but also the higher the grade is, the higher the price will be. Many strong magnet online retail stores also list more N42 neodymium permanent magnets on their websites. So N42 is perfect for green hands.

For example, when you start a new project that needs neodymium magnets and you don't know "What Grade Should I Choose", then grade N42 neodymium rare earth magnet is a good start to have a sample test. You can get the same strength as an N50 magnet by using a slightly larger N42 magnet or get the same strength as an N38 magnet by using a slightly smaller N42 magnet. But if you need the highest strength in the smallest possible size at room temperature, grade N52 or N55 is the strongest available.
