Magnetic Force

The force on a proton moving in a magnetic field is given by the formula: Where: - is the charge of the proton - is the velocity - is the magnetic field intensity - (since the proton is moving parallel to the magnetic field) Since , the force on the proton is: Thus, the force exerted on the proton is 0 N.

The magnetic force on a moving charge is given by: where is the charge, is the velocity, and is the magnetic field strength.
