Discuss the effects of changing the velocity ch... - SS1 Physics Electricity and Magnetism Question

Changing the velocity of a charged particle affects the magnitude of the magnetic force but not its direction. Doubling the velocity doubles the magnitude of the magnetic force. Changing the charge of the particle also affects the magnitude of the magnetic force. Doubling the charge doubles the magnitude of the force. Finally, changing the magnetic field strength affects both the magnitude and direction of the magnetic force. Doubling the magnetic field strength doubles the magnitude of the force, and changing the direction of the magnetic field changes the direction of the force.
