This is a very basic question which I can’t quite wrap my head around. Say you have a wire/coil in a magnetic field in such a way that if you apply a current in the wire it will move. So you charge up a capacitor or some other power source and discharge it through the wire, a force is generated and the wire gets some of that electrical energy converted into kenetic energy via F = BIL.
suppose I have the same charge, same everything but I increase the magnetic field by a factor of 10. The current should remain the same (right?) thus I have increased the force/acceleration by a factor of 10 and thus increased the final speed of the wire also by a factor of 10. Now this doesn’t make any sense, since in theory I could increase the magnetic field strength to some arbitrary number, meaning ”infinite efficiency”, so what am I missing here?
If it’s simply that the magnetic field affects the current, how exactly does it affect the current? (What formulas do I use to calculate the actuall current?)
Thank you in advance for clearing up this confusion in my brain.
