Does Magnetic Permeability Affect Magnet Lifting Power?

AI Thread Summary
Magnetic permeability does influence the lifting power of magnets, as materials with higher permeability can allow magnets to lift more weight compared to those with lower permeability, assuming equal density. The relationship between permeability and lifting capacity is not straightforward; it is more about how effectively a material channels magnetic lines. The force exerted by a magnet is proportional to the permeability ratio, indicating that higher permeability materials enhance magnetic interaction. However, permeability does not solely determine the weight a magnet can lift, as other factors also play a role. Ultimately, the ability of a material to interact with magnetic fields affects its lifting potential.

Does a material's magnetic permeability affect how much of said material a magnet can lift?

For example, say a magnet can lift 1 unit of weight of a material with a permeability of 2. If another material has a permeability of 4, could the same magnet instead lift 2 units of weight of this other material?

Or, does magnetic permeability only relate to the creation of electromagnets?

The force exerted by a magnet is proportional to (mu-1)/(mu+1) if mu is a constant
(independent of B).
 
I don't think that permeability is necessarily related to weight.

Having said that, it is true that of two materials of same density, a magnet would lift more weight of the one with higher permeability.

In other words, permeability is a measure of the friendliness of a material to magnetic lines...the ability to channel more and more magnetic lines through itself...and hence, the magnetic force between itself and a magnet would be proportional to the amount of linked magnetic lines.
 
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...
