Can a smaller magnet still repel with the same force as a larger magnet?

AI Thread Summary
The discussion centers on whether a smaller magnet can repel with the same force as a larger magnet. It is clarified that the repelling force depends on the magnetic moments of the magnets, not just their size. If a smaller magnet has a reduced magnetic moment, the total repelling force will decrease. The conversation also emphasizes the importance of using proper physical units instead of using kilograms to describe magnetic forces. Overall, a smaller magnet will not be able to support the same weight as a larger one if its magnetic moment is weaker.

Hi
Just wanted to know,

If I have two magnets of the same size with a pull force of say 30kg and use them to repel each other, the top magnet at a position close to the surface of the bottom magnet would be able to support around 30kg (I know repel force is not measured in kg). If I then replace the top magnet with a smaller one will it still be able to support around 30kg at the same position as it is still being repelled from the bottom one with around 30kg of force?

Thanks

The force between two magnets is (ideally) dependent on their orientation and the strength of their magnetic moments, which are not necessarily related to size. If you decrease the magnetic moments of one of the magnets, the total force is going to go down.

So why do you use it? Please stick to proper physical units.
 
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...
