AMSA AP Physics C lecture. I analyze a wire loop being pulled out of a magnetic field at a constant velocity. Variations on this situation are VERY common on the AP exam. I also demonstrate that the work/energy/power calculations made using the E&M quantities align with the results from mechanical work/energy/power.
