Exam-style question
Try this first
Explain how the magnetic force on a charged particle moving in a magnetic field is related to centripetal force.
Model answer
What a good answer should say
- The magnetic force acting on a charged particle moving in a magnetic field provides the necessary centripetal force to keep the particle in circular motion.
- This occurs because the magnetic force is always perpendicular to the velocity of the particle, resulting in a continuous change in direction.
Explanation
Why this works
This answer is strong as it connects the concepts of magnetic force and centripetal force, demonstrating an understanding of how forces interact in circular motion. The question tests the student's ability to apply their knowledge of forces in a magnetic context.
