From the post "Coriolis Force And My Left Foot", it was propose that when a mass transverses a gravitational field, \(g\) perpendicularly, it behaves like a negative charge and generates a \(g_B\) field around it perpendicular to its direction of travel. The direction of this field is given by the right hand screw rule, with consideration that this mass is equivalent to a negative charge.
This reversal of direction in \(g_B\) is due to the fact that two like masses are attractive whereas two like charges are repulsive. This is why, the moving mass generating a \(g_B\) field, is considered to be an equivalent negative charge. A positive test charge's interactions with the equivalent negative charge is attractive, just as a "positive" mass's interactions with another mass is attractive.
The established \(g_B\) field interacts with the "positive" mass in the same way as a \(B\) field interacts with a positive test charge.
In both cases, \(g_B\) and \(B\) field lines trace the direction of the force on a positive test particle; a moving positive mass and the north pole of a magnet/moving positive charge, respectively.
The sign reversal goes as far as the moving mass generating a \(g_B\) field. A positive mass interacts with the \(g_B\) field as a positive charge would interact with a \(B\) field.
Once the \(g_B\) field has been established, to think that a "positive" mass will somehow interact in a reverse manner with the field is absurd!
Have a nice day.
