Finding a theoretical magnetic dipole

[dev10251]

I recently completed a lab over magnetism and I need some help on my results. We were asked to find the magnetic dipole moment of small neodymium magnets that were about the size of a dime and around 1/4 inch thick. I found the experimental value using my results. However, I have not been able to locate a theoretical value. I realize that it changes with size and material, making it very unlikely to find. But if anyone knows where I can find the values of magnetic dipole moments of different magnets, please let me know. Thanks!

Unfortunately, the theoretical value of the magnetic dipole moment of a particular magnet will depend on its size and composition, and therefore cannot be found easily. The best you can do is to measure the magnetic field of your magnets using an appropriate instrument, such as a gaussmeter. You can then calculate the magnetic dipole moment from the measured field. Alternatively, you may be able to find published tables of magnetic dipole moment values for specific types of magnets.
