The minimum magnetic force on a moving electron occurs for motion

Question

Quizplus · Accepted Answer

The magnetic force on a moving charged particle is given by F = q(v x B), where q is the charge of the particle, v is its velocity, and B is the magnetic field. The magnitude of the magnetic force is given by F = qvBsinθ, where θ is the angle between v and B. When the particle moves parallel to the magnetic field (θ = 0°), sinθ = 0 and the magnetic force on the particle is zero. Therefore, the minimum magnetic force on a moving electron occurs when it moves parallel to the magnetic field.
