A charged particle moves with a constant speed through a region where a uniform magnetic field is present. If the magnetic field points straight upward, the magnetic force acting on this particle will be maximum when the particle moves

Question

Quizplus · Accepted Answer

The magnetic force on a charged particle is given by the cross product of the velocity of the particle and the magnetic field. This force is maximum when the angle between the velocity vector and the magnetic field vector is 90 degrees, which corresponds to the particle moving horizontally when the magnetic field is vertical.
