Creating a Magnet at Room Temperature

AI Thread Summary
Not every substance can be converted into a magnet at room temperature due to the nature of electron pairing, which cancels out magnetic properties. While all fundamental particles have magnetic characteristics, only certain materials exhibit coordinated magnetic behavior. The discussion suggests that isolating a molecule with an odd number of electrons could theoretically allow for magnetization. However, practical methods for achieving this across all substances remain unclear. The feasibility of creating magnets from all materials at room temperature is largely limited by their intrinsic properties.

How can every substance be converted into a magnet (at room temperature)?

No, not every substance can be converted into a magnet. Why do you say that ? May I know please ?

Are you asking a method to convert every substance to magnet ,or are you asking how it can be converted to magnet ?

Not sure the context of your question, but fundamentally every electron, proton and neutron is a tiny magnet. Most substances do not show coordinated magnetic behavior of the electrons (the strongest magnets) at room temperature.

... but I suppose, if you got down to one molecule of a substance and made sure it had an odd number of electrons (the electron magnets tend to pair and cancel themselves out), you could in theory convert the substance into a magnet.

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...
