Let's say I have two (-) charged beams.
According to observer 1:
Beam 1 is shot at 0.998 c.
Beam 2 is shot at 0.999 c.
>> Therefore, the beams are moving in the same direction.
Observer 2 is moving at 0.9985 c.
Observer 3 is moving at 0.9995 c.
According to observer 2:
Beam 1 is shot at -0.143 c [=(0.998-0.9985)/(1+0.998*(-0.9985)) c].
Beam 2 is shot at 0.200 c [=(0.999-0.9985)/(1+0.999*(-0.9985)) c].
>> Therefore, the beams are moving in opposite directions.
According to observer 3:
Beam 1 is shot at -0.600 c [=(0.998-0.9995)/(1+0.998*(-0.9995)) c].
Beam 2 is shot at -0.333 c [=(0.999-0.9995)/(1+0.999*(-0.9995)) c].
>> Therefore, the beams are moving in the same direction.
We can assume that for the sake of argument that all three observers are moving inertially.
Does the magnetic force act against the electric repulsion, as in two currents moving in the same direction? Or does the magnetic force act together with the electric repulsion, as in two currents moving in opposite directions?
Is it really possible that two currents can really be going in the same direction in one inertial frame and opposite directions in a different inertial frame without there being two different possible futures according to each frame?
In the two attached pictures below, I present a similar example, but this time it involves currents in loop wire rather than charged beams. The second attached picture depicts the view of the system from a non-inertial perspective. This differs from my newest example above, which assumes no non-inertial motion of any of the three observers.
