(a) Is any force exerted on the vertical sides of the loop thatyou used in the experiment and how does it affect the apparentmass? (Select all that apply.)

There is a force exerted on eachside of the loop that are equal in magnitude and opposite indirection.No force is exerted on the sidesof the loop.The lengths of the sides of theloop are much smaller than the bottom section and therefore theforce on the sides are negligible.The forceon the sides are not in the same direction in which the mass ismeasured and therefore it does not affect theresults.The force exerted on the sides ofthe loop cancel each other out.

(b) What would happen to the apparent change in mass if thedirection of the current is reversed? (Select all that apply.)

The magnitude of the apparentchange in mass is unaffected, but the sign isreversed.There is no change to either thedirection or the magnitude of the apparent change inmass.A decrease in apparent mass nowbecomes an increase, and vice versa.Itreverses the direction of the force vector on themagnet.

(c) What would happen to the apparent change in mass if the polesof the magnet were switched? (Select all that apply.)

The magnitude of the apparentchange in mass is unaffected, but the sign isreversed.The effect is the same asreversing the direction of the current.There is no change to either the direction or the magnitude ofthe apparent change in mass.It reverses thedirection of the force vector on the magnet.

(d) What would happen to the apparent change in mass if both thedirection of the current and the poles of the magnet were switched?(Select all that apply.)

There is no change to either thedirection or the magnitude of the apparent change inmass.A decrease in apparent mass nowbecomes an increase, and vice versa.Themagnitude of the apparent change in mass is unaffected, but thesign is reversed.It reverses the directionof the force vector on the magnet.
