The basic hypothesis of Topological Geometro-Dynamics (TGD) is that space-time is representable as a 4-surface in 8-dimensional space M^{4}+ ? CP_{2}. The notion of many-sheeted space-time forced by this hypothesis implies numerous new physics effects including gravitational anomalies, the possibility of negative energy space-time sheets making possible over unity energy production and classical communications to the geometric past. An essential element is the new view about the relationship between inertial and gravitational energy. The geometrization of the classical gauge fields in turn predicts the existence of long range color and electro-weak gauge fields, in particular classical Z^{0} field, which gives rise to macroscopic effects resembling those assigned usually with torsion fields. These fields are assignable to dark matter hierarchy rather than ordinary matter. In this article the strange findings about the physics of rotating magnetic systems are discussed in order to illustrate the new physics predicted by TGD.

In the beginning of the year 2002 I learned about strange effects related to rotating magnetic systems, and the model for these effects has evolved (and is still evolving) gradually during the year 2002 via trial and error process. Several new physics effects seem to be involved.
