Question

Maximum magnetic force occurs when electrons move • at non-right angles to the magnetic field direction. • perpendicular to the magnetic field direction. • in the same direction as the magnetic field. • opposite to the magnetic field direction.

Answer 1

The maximum magnetic force on electrons occurs when they move perpendicular to the magnetic field direction, as this is when the force calculated by the equation F = qv × B is at its maximum value.

Step-by-step explanation:

The maximum magnetic force on moving electrons occurs when they are moving perpendicular to the magnetic field direction. This is because the magnetic force exerted on charged particles, like electrons, is determined by the right-hand rule and is maximal when the angle between the velocity of the particles and the magnetic field lines is 90° (ninety degrees). The magnetic force is given by the equation F = qv × B, where F is the force, q is the charge, v is the velocity, and B is the magnetic field. The force is proportional to the sine of the angle between the particle's velocity and the magnetic field, hence when this angle is 90°, the sine function has a value of 1, which corresponds to the maximum force.
