Good information on magnets, magnetic energy, magnetic forces

AI Thread Summary
The discussion focuses on seeking reliable information about magnets, magnetic energy, and magnetic forces, as well as resources for purchasing or creating magnets, particularly rare Earth magnets. Participants share links to online sources that provide specifications and grades of Neodymium magnets, emphasizing the importance of reputable sites that prioritize material specifications over marketing. One suggested resource is KJ Magnetics, known for its detailed specifications. There is also a desire for more information on magnetic fields, forces, and related equations. Overall, the thread highlights a strong interest in understanding magnets and finding quality resources for both purchasing and DIY projects.

Can anyone point me in the direction of good information on magnet's, magnetic energy, magnetic forces. Or does anybody have a good understanding of this?

Would really like to find somewhere that I can order magnets. Or better yet, make good one's myself, or find out how to find rare Earth magnets.

Thank you for any help on this. If anyone has a great understanding of magnets, I have a ton of questions.

I found an online source that lists the various grades of Neodymium magnets they sell. They list specifications. http://www.magnetsales.com/index.htm"

Found that site too. Would like to find some info on magnetic fields, forces, and equations for these.
 


This might be a start

Ya, know. I don't know why I gave you that above link. I must have got them comfused. If I am looking for a reputable site for materials, if they manage specifications rather than yacking up how wonderful their stuff is, I feel more comfortable departing with cash. This is the one I was thinking of

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
