Good observation Bill. The magnetic field is completely expelled from a superconductor. Uo=zero
The electric field is completely confined. e0 = infintie The range and strength of the two fields is a function dimensions of the superconductor. As you stated Bill, a static field induces a current. Symmetry is restored to the laws of electromagnetism. The superconductor is a macroscopic elementary particle. Circulating currents are pinned by placing deflects in the superconductor. These defects pin the circulating currents to the superconductor. Pinning must likewise attach local fields to the stationary quantum states. In an electron this pinning discontinuity exists at the classical radius of the electron. The transitional quantum state releases the grip of the pinning discontinuity. The electromagnetic flux then flows strongly and at range. The other forces must also flow strongly at range. An analysis of the spectrum of hydrogen (in IE this Sept) has shown that one more thing must be added to adjoin all of the force within the superconductive relationship. This thing is vibration. The frequency of the vibration depends on the size of the superconductive structure. The constant is 1.094 million metes / second. The vibration releases the grip of the pinning discontinuity. The amplitude of the vibration determines the probability of transition. Then, maybe I’m wrong.
