## How to compute the magnetic force between two electromagnets?

(OP)

I wanna compute the magnetic forces between two solenoids with iron cores, is there any analytic formula for this?

I guess that dipole-dipole interaction "https://en.wikipedia.org/wiki/Force_between_magnet..." can be used, but I don't know how to compute the dipole moment for solenoid with iron core.

Can you use Maxwell's Equations to work out individually what the Magnetic Field strength is for both individually?
