Question
Figure a shows a loop model for an electron orbiting in an atom while in a nonuniform magnetic field ext. In Figure b, charge -e moves counterclockwise; the associated conventional current i is clockwise. How does the magnitude of the net force on the current loop change in the following situations? (Select all that apply.) -increases if the magnitude of Bext is increased -decreases if the magnitude of Bext is increased -remains constant if the magnitude of Bext is increased -increases if the divergence of Bext is increased -decreases if the divergence of Bext is increased -remains constant if the divergence of Bext is increased

decreases if the magnitude of Bext is increased...because the the current will face perpendicularly to the magnetic field and B ext will be perpendicular to the given coil...so as the Bext is increased to maintain the net external force on the coil should be decrease.
