Electromotive force and Lorenz Force HELP

Click For Summary
SUMMARY

The discussion centers on the interaction between a rectangular coil and an infinitely long wire carrying a constant current. When the coil moves perpendicularly to the wire, the induced electromotive force (EMF) generates a current in the coil. This current interacts with the magnetic field produced by the wire, resulting in torque on the coil. Additionally, variations in the magnetic field can produce a net force on the coil, indicating that the Lorenz force is not zero despite the presence of EMF.

If I have a rectangular coil with no current flowing on it traveling at a velovity v; and I have an infinetely long wire with a constante current i on the same plane of the rectangular coil which velocity v is perpendicular to the wire, is the lorenz force equal to zero because I have only electromotive force?

That's a little complicated. The induced EMF will set up a current in the loop and that will interact with the primary magnetic field (from the wire). The primary effect will be torque acting on the loop but gradients in the applied field will yield a net force on the loop.
