An expression for the magnetic field strength

B

at the point between the capacitor plates indicates in figure express

B

in terms of the rate of change of the electric field strength

ie,\;dE/dt

between the plates

View answer and explanation

Correct option: B

\frac{{{\varepsilon _0}{\mathrm{\mu }_0}r}}{2}dE/dt

Option B (

\frac{{{\varepsilon _0}{{\mu }_0}r}}{2}dE/dt

) is correct because it represents the magnetic field strength between the capacitor plates in terms of the rate of change of the electric field.
