We argue that in the general relativistic calculation of planetary orbits, the choice of a reference frame which is an obligatory condition in the Newtonian approach is replaced by an appropriate boundary condition on the solution of Einstein equation. Implications of this observation on the nature of rotation and the physical interpretation of the metric tensor are discussed.
The phenomenon of unipolar induction consists in generating electric field by uniformly rotating permanent magnets made of either conducting or dielectric substance. The origin of the field around conducting magnets is explained and calculated in Sect. 1. Dielectrics are considered in Sect. 2, where the role of the electric moment due to moving magnetic dipole moment is clarified. Sect. 3 is devoted to the description of the effect in the corotating frame of reference. In Sect. 4 the theory is applied to the Earth core and it is shown that the calculated electric field falls precisely into the range of the ambient electric field observed in the Tethered Satellite System mission of NASA. In the last paragraph I reflect on whether flyby anomaly might be attributed to an electric effect.
Based on the principle that arrival time and position are simultaneously measurable quantities a simple formula is derived for the arrival time probability density in nonrelativistic quantum theory.
