Exam-style question
Try this first
What is the path of a charged particle moving in a uniform magnetic field? Scenario focus: inverse-square reasoning in a distinct A-Level Physics fields context; identify the field quantity, source, direction, and unit before selecting the answer.
- A.Straight line
- B.Circular path
- C.Elliptical path
- D.Random path
Model answer
What a good answer should say
- Circular path
Explanation
Why this works
The correct answer is Circular path. This is correct for Magnetic fields because the stem is testing inverse-square reasoning; the chosen option keeps the field quantity, source interaction, direction, and unit consistent.
The alternatives are weaker because they mix gravitational, electric, magnetic, orbital, or transformer ideas, or they attach the right number to the wrong physical meaning.
