Parallel-plate capacitor by circular plates

Reference no: EM13658586

As a parallel-plate capacitor by circular plates 18 cm in diameter is being charged, the current density of the displacement current in the region among the plates is uniform and has a magnitude of 19 A/m². (a) Compute the magnitude B of the magnetic field at a distance r= 42 mm from the axis of symmetry of this region.(b) Compute dE/dt in this region.
