Question

Quizplus · Accepted Answer

When a positively charged particle (like a hydrogen atom that has lost its electron) moves in a magnetic field, it experiences a force perpendicular to both its velocity and the magnetic field direction. Using the right-hand rule, with the thumb pointing east (direction of motion), and the fingers pointing north (direction of the magnetic field), the palm faces up, indicating the force (and thus deflection) is upwards.
