Joseph Newman has experimentally derived a magnetic field from a coil connected to high potential. As shall be seen in the following, this is a complementary effect to that found in ferromagnetic resonance. This effect does not contradict Oersted, since it depends on an entirely different set of suppositions unknown to Oersted and now known as a part of condensed matter physics.

After studying ferromagnetic resonance theory for nine years it comes as no surprise to me that Newman has proven a corollary to the relationship of fields and spinning dipoles in matter. He has completed the symmetry.

While it is well known that magnetic fields cause the precession of elementary magnetic moments and that precessing moments produce a magnetic field, the role of the electric field, the other half of the symmetry, has not until now been explained.

An electric field is known to cause spinning electric dipoles to precess. Precessing elementary electric dipoles are, at the same time, precessing elementary magnetic moments. Precessing electrons have BOTH characteristics.

The ratio e/m means two things simultaneously. Of course, charge to mass, influenced by electric fields, but also the ratio is the ratio of magnetic moment to angular momentum of the electron, influenced by magnetic fields.

We are not dealing here with the usual source of magnetism, a conductive flow of electrons. Rather, it is the precession of electrons that is crucial. The precession tends to align the magnetic moments parallel; by superposition, a net magnetic field emerges.

Newman's effect, then, is that a high electrical potential across a solid copper coil of radius r causes the precession of electrons in the copper, yielding a magnetic field.

If the angular frequency of precession is w and the ratio e/m is y (mksa units) then the magnetic flux density is:

B = w / y

An identity for B is:

B = E / wr

where E is the applied electric field.

Solve for w in the first equation (w = yB) then substitute this expression into the identity for w. Multiply both sides by B, and,

B^2 = E / yr or,

B = sqrt(E / yr).

Maxwell's equations are linear because they refer to a vacuum. The non-linearity between E and B above is connected with the presence of mass and spin.

Can very large electric fields be applied without breakdown? Theoretically, if r = 1m and E = 1.76 x 10^11 V/m, B = 1 Tesla.

The current through the coil is marginal to insignificant as related by Newman. Power = V^2 / R so the length and diameter of the copper forming the coil must be chosen to minimize the resistance.

B will alternate (pole switch) with an alternating potential.
