What is the direction of the magnetic force on the proton? What is the magnitude of the magnetic force on the proton?
A proton is traveling west, with speed 4 x 10^5 m/s. The proton encounters a magnetic field of 0.34 T going east, due to current running in a nearby wire.

1 Answer
Magnitude of the magnetic force on the proton is understood as magnitude of the force experienced by the proton in the magnetic field which has been calculated and is
Explanation:
Force experienced by a charge particle having charge
Given a proton moving West encounters a magnetic field going to East. As there is no external electric field, above equation reduces to
As the velocity vector of proton and magnetic field vector are opposite to each other, angle
We know that
Consequently the cross product vanishes.
