The grade of a neodymium magnet, such as N35, N42, N45, or N52, indicates its magnetic strength. Higher numbers correspond to stronger magnetic fields. For example, an N35 magnet has a lower magnetic strength compared to an N52 magnet. The “N” stands for neodymium, and the number reflects the maximum energy product of the magnet, measured in megagauss-oersteds (MGOe). N35 magnets are often used in applications where moderate strength is sufficient, while higher grades like N52 are preferred for tasks requiring maximum force. At Magnet Store, we offer a wide range of grades, ensuring you get the right balance of strength and performance for your project, whether you need an N35 for light-duty use or an N52 for heavy-duty industrial applications.

All off-the-shelf orders are dispatched as quickly as possible. Our team will ensure all orders placed before 1pm (Monday – Friday excluding bank holidays) are sent the same day. Each packer will inspect the item quality as they are packing and dispatching order to ensure you receive only the best quality goods.

Whether you’re a business looking for bulk orders or an individual in need of specific magnets for a project, we are here to help with expert advice and tailored solutions.

Yes, heat can damage neodymium magnets by reducing or even completely destroying their magnetic strength. Neodymium magnets have specific temperature limits, and when exposed to temperatures beyond these limits, they begin to lose their magnetism. Standard grades typically withstand temperatures up to around 80°C, but if your application requires higher resistance, we can custom-manufacture neodymium magnets designed to withstand much higher temperatures. This ensures they maintain their magnetic strength even in extreme heat conditions.

A magnet’s coercivity, or “Hci” refers to the magnets ability to withstand demagnetisation through high temperatures. When manufacturing magnets, a magnet’s coercivity is defined by the letters after the grade, for example, the “M” in N52M. Any magnets without a letter after the grade (i.e N35, N45, N52) have a heat tolerence of up to 80°C.

Available Heat Tolerences

• No letter – 80°C
• M – 100°C
• H – 120°C
• SH – 150°C
• UH – 180°C
• EH – 200°C
• TH – 220°C

Although Neodymium was discovered in 1885 by Karl Auer, it was only in 1983 that Neodymium Magnets as we know today was invented almost simultaneously by General Motors and Sumitomo Special Metals and these strong and versatile magnets have spearheaded innovation in the green energy, medical and technology sector. These Neodymium magnets are small but generate an incredible amount of power and it’s this power that led to the miniaturization of many technologies like drills, heavy machinery, smart phones, sound speakers, computers and many more. They are commonly used in industries such as retail, engineering, plastic moulding, DIY, crafts, furniture making, science research & experimentation, education and many more.
