N42 Neodymium Magnet Enquiry & Grade Series N42M, N42H, N42SH, N42UH

Grade N42 neodymium magnet is an ideal DIY Parts & Options. It can be used as closure, mount, connector, holder and stand etc. helping you for the development of new inventions and making your life easier. Therefore, you can find permanent magnets on many novel products in Kickstarter. Most of our customers directly pointed out that they need N42 magnet at their first magnet enquiry.

I am interested in buying neodymium square magnet, 12.5mm x 12.5mm x 2.5mm, Neodymium rare earth magnet, N42 grade. I would like pricing for 1000 and 10000 magnets.

Why so many customers choose N42 neodymium rare earth magnets?

That's because 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, the higher the price.

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 which need neodymium magnet and you don't know "What Grade Should I Choose", grade N42 neodymium rare earth magnet is a good start to have 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 small 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.

Shape of N42 Super Strong Neodymium Magnets

What does grade n42 magnet mean?

The grade N42 means 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 showed 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. And currently, the highest grade of neodymium magnet available is N55, 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℃. Thereinto, N42SH high working temperature neodymium magnets are widely used on motor.
