My first post so please forgive me if I am already breaking some rules ;)
This may apply to positive or negative particles: We know that equal charges repel each other to the value of Coulomb force F=kqq/r^2.
What I would like to know is if a magnetic force between two (non-moving, but rotating) equal charges is also always repelling? (or any other force?)
Assume that the particles have E and B fields, and they rotate in one place. It is allowed to orientate the particles in different directions if necessary.
So if for example a negative particle facing in the x-direction is close to a negative particle facing in the y-direction, their E and B fields are perpendicular. Because they are rotating, and their fields are crossing, I am expecting a magnetic effect, but will it also be a repulsive force? Or is there some orientation that could make this magnetic force negative?
Are there equations that I could use to analyse such a situation?
Is there another force, like gravitational force, that could have two equal charges attracting each other? It does not need to overcome the Coulomb force.
