Application +4 | -1

The magnetic field between the plate of a capacitor when

r < R

is given by

View answer and explanation

Correct option: A

\frac{{{\mathrm{\mu }_0}{i_D}r}}{{2\mathrm{\pi }{R^2}}}

Option A (

\frac{{{\mathrm{\mu }_0}{i_D}r}}{{2\mathrm{\pi }{R^2}}}

) is correct because it represents the magnetic field inside the capacitor plates, derived using Ampere-Maxwell's law.
