A spherical capacitor is formed by two concentric metallic spherical shells. The capacitor is then charged so that the outer shell carries a positive charge and the inner shell carries an equal but negative charge. Even if the capacitor is not connected to any circuit, the charge will eventually leak away due to a small electrical conductivity of the material between the shells. What is the character of the magnetic field produced by this leakage current?

Options

ARadially outwards from the inner shell to the outer shell.
BCircular field lines between the shells and perpendicular to the radial direction.
CNo magnetic field will be produced.
