The Likes Of Hall Effects

This is how a transient field as the result of spinning negative particles around a positive nucleus might align and be detectable. A negative particle spinning around a positive nucleus and together revolve around another nucleus (positive or negative) in an elliptical orbit.

A positive field will be required to push the positive nucleus towards a flat surface of the containing material.  This field can be along the direction of the transient field, perpendicular to the flat surface or be perpendicular to the transient field, parallel to the flat surface.

It is likely that the center particle about which the spinning pair revolves, is part of the solid lattice of the material.  This requires that the lattice be sufficiently sparse to accommodate the revolving pair of particles.

Happy Lunar New Year!  Go crazy.
