This is a homework question that I have stuck for a while and couldn't able to come up with the correct answer.
So here is the question,
My thoughts towards this question
- When I move the rod PQ with a constant velocity ,the area of triangle RPQ inside the magnetic field increases .
- Once the area inside the magnetic field increases E.M.F induces also increases.
- Since induce E.M.F get increased the induced current should also be increased.
So according to my arguments I choose the answer as the third one. But the answer in marking scheme is the first one.
What I have done wrong. Please explain this question with details.
