In General Analogues for aiki principles in electromagnetic f Entry Tools Rate This Entry

[This immediate blog discussion follows a forum discussion on gyrodynamics and the principle of juji, the "cross shape" +. It is put here in blog form for those who care about the technical intricacies of such things and exploring non-aiki analogues of aiki principles, and other observations that may shed light on Aiki priciples and WHY they work the way they do. I will repost the gyrodynamics portions of this discussion immediately following. While the facts related are sound as far as they go, the application of everything here is speculative and subject verification in actual aikido practice. Choose wisely, therefore, and ask your own teacher. ]

You cannot have magnetic flux without electric current somewhere within meaningful inverse square law range, and you cannot have electrical current without magnetic flux similarly situated. But they are always 90 degrees out of phase from one another. (right hand rule) But you can have observed purely electrical action or observed purely magnetic action because of their existence in differing phases. The potential always exists for the correlative action of the other at the same field strength in each circumstance; but it remains potential (virtual) until realized by appropriate conversion of its form or phase.

Of course, you cannot measure a field directly without inducing current or flux. Heisenberg's law still applies. An electric field exists without magnetic flux. Magnetic flux is only created by those electrons starting to move and thus creating current. One can be used to measure the other. But electric fields can be measured indirectly without inducing current or flux.

Photons possess neither mass nor charge and yet they excite electrons and electrons, when sufficiently excited, emit them without creating current, but revealing their charge state. Because of two potential polarizations, photons also preserve the phase distinction between the joint magnetic and electric fields to which they relate. In a sufficiently strong electric field, electrons spontaneuously emit photons and tend to ionize as they do that (with a local deielectric current, but n ...More Read More
