I'm not currently taking any physics courses, and Googling has left me the same way I was before I started searching. Would anyone happen to know the rate of relative acceleration of a magnetically charged particle in relation to another particle of some charge?
see http://en.wikipedia.org/wiki/Coulomb's_law
One thing not mentioned there (I think) is that the force depends on surrounding material. There should be another epsilon in that formula (just without a 0). I do not know how it is called in English though..
Your question is a bit confusing. A particle may have an electric charge but not a magnetic charge. This was probably ne555's point but he did not elaborate.
A magnetic field exerts a force on an electrically charged particle traveling through it.
If both electric (E) and magnetic (B ) fields are present then use the Lorentz force law:
F = q*( E + vxB )
for a particle with charge q and velocity v.
Use Newtons 2nd law to find the acceleration = F/mass
Google coloumb's law. If I interpreted what you're asking for correctly this might give you what you want.
That's the best I can think of with an HS physics education.
Edit: I guess hamsterman already said that though...
With this equation you should be able to find relative acceleration.
