Electon's spin
follows the direction of the external (i.e. orbital) magnetic field
unless it gets opposite ...
Electrons in hydrogen atom are attracted by the nucleus but
less than they should be.
It seems that "empty" vacuum is
filled with something.
The plastic stick when electrically charged,
attracts pieces of paper; it also attracks blade,
unless the blade is not in vacuum.
1. At rest the path is 2L, and time t=2L/v, where
v is the velocity of the ball
2. In movement, the path is longer, but also the velocity is higher (unless
inrelativity conditions)
See the same from other direction:
Only 1/r2 field assures closed orbits of planet.
Presence of Sun deforms space geometry - the field is not 1/r2 like: Mercurys' orbit is open.
Try the following gravitational and non-gravitational funnels.
