A conductor moving in the magnetic field \(B\) and the induced current is \(I\). If the magnetic field is doubled the induced current will
- A remain the same
- B be half
- C be doubled
- D be four times
Answer & Solution
Correct Answer
(C) be doubled
Step-by-step Solution
Detailed explanation
Given, initial magnetic field \(=B\) Initial induced current \(=I\) Final magnetic field, \(B^{\prime}=2 B\) Final current \(=I^{\prime}\) Since, emf, \(\varepsilon=B l v \sin \theta=I R\) where, \(B\) is magnetic field, \(l\) is length of conductor, \(v\) is velocity, \(I\) is…
