Force of a solenoid on a magnet?

AI Thread Summary
To calculate the force between a solenoid and a magnet inside it, one must consider the solenoid's parameters, including the number of turns (n), length (l), and current (I). The discussion clarifies that while a solenoid can exert torque on a magnet, it does not produce a net force on the magnet itself. The magnet's position, specifically its distance (d) from the solenoid's center, is also relevant in understanding the interaction. Overall, the key takeaway is that the interaction involves torque rather than a direct force. Understanding these principles is essential for accurate calculations in electromagnetic applications.

I'm trying to calculate the force between a solenoid and a magnet inside that solenoid. Would someone be able to explain how I would be able to calculate the force a solenoid of n number of turns and l length with a current I running through it would put on a magnet whose center is a distance d from the centre of the solenoid? any help would be much appreciated. Thanks!

There wouldn't be a force on the magnet. Torque yes, but no net 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...
