We have many other sizes available. Call today and allow us to help you find the correct size for your application.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 ourMagnet Summary Page. The surface field of each of our stock magnets is also listed on that samepage. We also offer anonline magnet calculatorto help you estimate the pull force and field strength of magnets at any distance from the magnet.
