Rare Earth Magnets Typical Demagnetization Curves

Typical Demagnetization Curves

The six tables on this page reflect the demagnetisation curve for the different types of magnetic grades. Each table incorporates a number of grade strengths within each of the types of grades. For instance, the N grade table includes N30 N33 N35 N38 N40 N42 N45 as these are the standard grades available.

N grade magnets account for the majority of all Neodymium magnets produced and sold. However the following grades (NM, NH, NSH, NUH, NEH) have been developed to withstand higher operating temperatures than standard N grade magnets are able to perform in. Regardless of the letters in the grade, the general rule is the higher the number the more powerful the magnet. The number comes from an actual material property, the Maximum Energy Product of the magnet material. For more information about the grades available please take a look at the Magnet Grades article in our Knowledge Base page.

The full range of Neodymium magnets available to purchase online can be found in our Rare Earth category. There are thousands of magnets to choose from however you can use the filters such as shape, grade, strength or even coating to narrow down the results. If there is a particular magnet you require that is not listed please get in touch. We will do our best to assist you in sourcing the magnet or organising a custom batch of magnets.

The information expressed in these charts along with more detailed information can be viewed in a tabulated form. Please refer to the Rare Earth Typical Magnetic Properties page for this information. Our team is always on hand should you have any further questions.
