Calculating Magnetic Force on a Steel Object in a Solenoid

AI Thread Summary
To calculate the magnetic force on a steel object in a solenoid, the relationship involves the magnetic field strength (B), the mass of the object (M), and the distance between the solenoid and the object. In the example provided, with a magnetic field of 400 Tesla and a 2 cm gap, the specific force can be determined using the formula F = B * M * ... (additional parameters needed). Further clarification on the mass of the steel cube is necessary to compute the exact force. Understanding the scenario's parameters is crucial for accurate calculations.

Hi There
I want To calculate magnetic force in Solenoid. I need to relation between Force and (tesla, weight iron, and ...)
F== B*M* ...
is anybody here can help me ?

Can you be more specific and detailed? I'm not sure I understand the scenario.

Sure
For example we have a Solenoid with Magnetic filed B= 400 Tesla , please tell me that if I have a cubic from steel , and the apace between solenoid and cubic is 2 cm, how many force will apply on cubic ?

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...
