When a metal road of length \(l\) is placed in a magnetic field \(B\) and moved with velocity \(v\) perpendicular to the field, then the induced emf across its ends is
- A B/v
- B \(\frac{B l}{v}\)
- C \(\frac{v}{B l}\)
- D \(e B l\)
Answer & Solution
Correct Answer
(A) B/v
Step-by-step Solution
Detailed explanation
The given situation is shown below \(\therefore\) The distance covered by the rod at time \(d t\) is \(\mathbf{v} d t\). \(\therefore\) The area covered by the \(\operatorname{rod} \mathbf{A}=\mathbf{v} d t \times l\) In time \(d t\), time magnetic flux linked with the rod,…
