Is There an Equation for the Force on a Charged Particle in a Magnetic Field?

[Kracatoan]

Just wondering, is there an equation for the force exerted on a charged particle moving perpendicularly through a magnetic field?

Yes there it is. You might have heard of Lorentz force equation.
Please check Wikipedia's page on it and refer any standard textbook for detailed explanation.

Ah I see, but how do I get the vector cross product for something like a beta particle passing though a magnetic field which is perpendicular to it?

The direction is found using (qv)x(B). So depending on the sign of q, your vector will point in one of two possible directions.

Ah Excellent. Thanks you two.
