High Coercive Force N33 N35 N42 N45 N48 Ceiling Fan Magnet
Introduction
Neodymium Magnets (Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals. These rare earth magnets are extremely strong for their small size, metallic in appearance and found in shapes of blocks, discs and rings. Need a magnet size not listed? We have many other sizes available. Call today and allow us to help you find the correct size for your application.
Demagnetization
Rare Earth magnets have a high resistance to demagnetization, unlike most other types of magnets. They will not lose their magnetization around other magnets or if dropped. They will however, begin to lose strength if they are heated above their maximum operating temperature, which is 176°F (80°C) for standard N grades. They will completely lose their magnetization if heated above their Curie temperature, which is 590°F (310°C) for standard N grades. Some of our magnets are of high temperature material, which can withstand higher temperatures without losing strength.
Strength
If you've never handled neodymium magnets before, you will be amazed at their strength. Neodymium magnets are over 10x stronger than the strongest ceramic magnets. If you are currently using ceramic magnets in your project, you could probably use a much smaller neodymium magnet and have greater holding force. You can get an idea of the relative strength of each of our magnets on our Magnet Summary Page. The surface field of each of our stock magnets is also listed on that same page. We also offer an online magnet calculator to help you estimate the pull force and field strength of magnets at any distance from the magnet.
