| Abstract: | The relationship between the induced electric field and the current that sets up the field is deduced and applied to calculate the magnetic field from the current in windings of spherical shaped coils and to confirm the conclusion that the mutual inductances between any two coils are equal to each other. |

| Keywords: | induced electric field vector potential magnetic fields |
