I am interested in finding the force and torque exerted onto a PM by another PM within the vicinity.

So I am just wondering if I could use the same force/torque equations (e.g. for the force as shown below-sorry for the messy typeset) between two axially magentised PMs for the diametrically magnetized ones as well:

I see that most cases are calculated for axially magnetized PMs. I am working with two diametrically magnetized NdFeB magnets and got pretty confused as to how I should compute the dynamics (force and torque of one PM (primary) when another is closely present).. as well as how far should the NdFeB PMs be apart so I could ignore the effect of the other PM onto the primary PM. Also, I am not sure if the generally available equations for the axially magnetized PMs can be used in my case.

I am thinking that the magnetization, M through the diametrically and axially magnetized PMs is different in direction, thus the force and torque on either one of the two PMs might be different with different PM dimensions and positions.

Looking forward to hearing from anyone with ideas and advice =) Thank you very much!
