MCQ
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
- ANo variation
- B$t^3$
- ✓$t$
- D$t^2$
✓
Answer
Correct option: C.
$t$
c
$E \propto t^{2}$
$E \propto t^{2}$
$B=\frac{d E}{d t} \quad B=\frac{d}{d t}\left(t^{2}\right), B=2 t$
$B \propto t$
