Homework Statement
Hello all,
If we have a bar that is perpendicular to a magnetic field, and that bar is being pushed to the left via an applied force, all the while a current (due to a voltage source and resistor) runs down through the wire. Therefore, there would be a total force comprised of a magnetic force due to the current and an applied for, both directed to the left.
My question is: since another magnetic force develops to oppose this motion and allow dv/dt=0, it will have to have current go UP through the metal rod, and therefore oppose the initial current that was supplied by the voltage source, correct?
Hopefully that makes sense without the need of a picture. If not, please let me know and I will attempt to draw a picture. Regards, Sandy.
