NEET · Physics · STD 12 -6. Electromagnetic induction
Inside a parallel plate capacitor the electric field \(E\) varies with time as \(t^2\). The variation of induced magnetic field with time is given by
- A No variation
- B \(t^3\)
- C \(t\)
- D \(t^2\)
Answer & Solution
Correct Answer
(C) \(t\)
Step-by-step Solution
Detailed explanation
\(E \propto t^{2}\) \(B=\frac{d E}{d t} \quad B=\frac{d}{d t}\left(t^{2}\right), B=2 t\)
