Exam-style question
Try this first
If the magnetic field through a coil is increasing, what direction will the induced current flow according to Lenz's law?.
- A.Clockwise
- B.Counterclockwise
- C.No current will flow
- D.It depends on the coil's orientation
Model answer
What a good answer should say
- Counterclockwise
Explanation
Why this works
If the magnetic field through a coil is increasing, Lenz's law states that the induced current will flow in a direction that opposes this increase. If we assume a conventional current, this would typically result in a counterclockwise direction.
