Exam-style question
Try this first
In a scenario where the magnetic flux through a loop is decreasing, what will be the effect on the induced current according to Lenz's law?.
- A.The induced current will flow to maintain the magnetic flux.
- B.The induced current will flow to decrease the magnetic flux further.
- C.No induced current will occur.
- D.The induced current will flow randomly.
Model answer
What a good answer should say
- The induced current will flow to maintain the magnetic flux.
Explanation
Why this works
According to Lenz's law, if the magnetic flux through a loop is decreasing, the induced current will flow in a direction that opposes this decrease, effectively trying to maintain the magnetic flux.
