I'm not well versed in magnetic force application and was wondering if there is any general equation that roughly approximates the braking force eddy currents apply on this rotating disk. I imagine a few parameters this problem would depend are as follows:

- magnetic field generated by each magnet

- angular velocity/angular acceleration of the rotating disc

- volume of rotating disc

- mass of rotating disc

- some magnetic property of the metal disc

- distance the magnets are from the rotating disc

- point of application of eddy forces in relation to the center of rotation

I've done some preliminary literature review however some of the studies seemed to be a bit over my head. Any help would be greatly appreciated!
