Calculating Force Created by Opposing Magnets

AI Thread Summary
The discussion focuses on calculating the force generated by opposing magnets influenced by electric energy. A formula is sought that incorporates the size of the magnets, the current supplied, the angle between them, and the distance separating them. The Biot-Savart law is recommended for calculating the magnetic field based on wire geometry. The force can then be determined using the equation dF = I dL x B. Understanding these relationships is crucial for accurate force calculations between magnets.

Amount of force 1 magnet with"x"electric energy can create against an opposing magnet

is there a formula which can allow me to calculate the amount of force which can be created by two opposing magnetic fields with a certain amount of electrical current?

does the size of the magnet have much to do with the maximum amount of force the field can create ?

maybe some formula involving : SIZE of magnet, amount of current supplied, ANGLE (degrees) of opposing magnet with the same energy and DISTANCE between these two magnets?

Use the Biot-Savart law to calculate the field from your wire geometry and then use dF = I dL x B to determine the force.

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...
