Exam-style question
Try this first
A proton is moving in a magnetic field directed into the page. If the proton is moving to the right, what is the direction of the magnetic force acting on it?.
Model answer
What a good answer should say
- The magnetic force acting on the proton is directed upwards.
Explanation
Why this works
This question tests the understanding of the right-hand rule for charged particles in a magnetic field. By applying the rule, the thumb points in the direction of the velocity (to the right), and the fingers point in the direction of the magnetic field (into the page), resulting in the palm pointing upwards, indicating the direction of the force.
