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

Explanation / Answer

if the Bext is increased the net force also increases as we know F= qv*B if the Bext ids reduced then the net force also decreases and if we keep the net B constant then the net force also remains constant
