Magnetic Force (Vector Cross Product)

Use the vector cross product to determine the magnetic force on a positive charge moving through a magnetic field. This force equals charge times velocity (qv), crossed with the magnetic field (B). Visually check your cross product by entering the force vector and inspecting the diagram. The force vector should be perpendicular to both B and qv, directed according to the right-hand-rule.
