A charged spherical capacitor slowly discharges as a result of the slight conductivity of the dielectric between its concentric plates. What are the magnitude and direction of the magnetic field caused by the resulting electric current?
Is there a magnetic field induced by a solid charged sphere surrounded by a spherical shell (oppositely charged) with a very weak conducting dialectric inserted in between (current going outward, from solid sphere to outer shell). Would it still induce a magnetic field? I can''t picture what...
Uniform Electric Field: In an ideal spherical capacitor, the electric field between the spheres is uniform, assuming the spheres are perfectly spherical and the charge distribution is uniform. However, in practical cases, deviations may occur due to imperfections in the spheres or non-uniform charge distribution. High Capacitance: Spherical capacitors can have relatively high

• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
A real capacitor is finite in size. Thus, the electric field lines at the edge of the plates are not straight lines, and the field is not contained entirely between the plates. This is known as edge effects, and the non-uniform fields near the edge are called the fringing fields.
