Note: whenever dielectricity is used, it means the inertial plane or better a centripetal radial (counterspatial) inertial plane.(see more about this later)
Magnetism radiates and thus creates space within the radiated field (sphere). A toroid is an expression of space. Space is NOT empty. Nor magnetism, nor di-electricity ends in space but in counter space. The magnetic and the dielectric are two opposed fields (think: motion towards Walter Russell's cathode and anode) acting in the same space sphere, pulsing back and forth, giving rise to different frequencies and amplitudes. They are 'not seen' when in equilibrium. Space does nothing and acts on nothing. It is an effect. Magnetism is the (polarised) end terminus of electricity. Magnetism is centrifugal en electricity is centripetal towards the nucleus. The smaller the space, the bigger the dielectric capacitance (higher potential).
Note also that nature's space spheres are hyperboloids!
