FAQs
What is the magnetic force on a stationary charge? Zero. A charge must be moving to experience a magnetic force.
When is the magnetic force maximum on a moving charge? When the charge moves perpendicular to the magnetic field direction.
Can magnetic force change a particle’s speed? No. Magnetic force only changes direction, not speed or kinetic energy.
