The lorentz foce has been bothering me. Becouse it seems to sugest an abosolute velocity. Say you have tw parrellel wires, with equal current running in the same direction. According to Lorrentz force, they attract. Now, the two wires are plasma. The curents are running side by side, at equal velocity (equal current). Everthing is the same. The electrons should still attraced. A little wierd, but not too bad. NOW. Simply remove the plasma. Two streams of electrons, in space. The Lorentz force should still attracked, as the only thing that has changed between these experements is the medium. EXCEPT in space, there is no medium, which means that there is NOTHING to compare the speeds to. THe electrons are still traveling at the same velocity (which no longer makes sence) And they are still atrackting. See what I am getting at? Anyone know where my thinking is wrong? Thanks!
