Question
a) Is any force exerted on the vertical sides of the loop that you used in the experiment and how does it affect the apparent mass? (Select all that apply.)
The force on the sides are not in the same direction in which the mass is measured and therefore it does not affect the results.
No force is exerted on the sides of the loop.
The force exerted on the sides of the loop cancel each other out.
There is a force exerted on each side of the loop that are equal in magnitude and opposite in direction.
The lengths of the sides of the loop are much smaller than the bottom section and therefore the force on the sides are negligible.
(b) What would happen to the apparent change in mass if the direction of the current is reversed? (Select all that apply.)
It reverses the direction of the force vector on the magnet.
A decrease in apparent mass now becomes an increase, and vice versa.
There is no change to either the direction or the magnitude of the apparent change in mass.
The magnitude of the apparent change in mass is unaffected, but the sign is reversed.
(c) What would happen to the apparent change in mass if the poles of the magnet were switched? (Select all that apply.)
The magnitude of the apparent change in mass is unaffected, but the sign is reversed.
The effect is the same as reversing the direction of the current.
There is no change to either the direction or the magnitude of the apparent change in mass.
It reverses the direction of the force vector on the magnet.
(d) What would happen to the apparent change in mass if both the direction of the current and the poles of the magnet were switched? (Select all that apply.)
It reverses the direction of the force vector on the magnet.
The magnitude of the apparent change in mass is unaffected, but the sign is reversed.
There is no change to either the direction or the magnitude of the apparent change in mass.
A decrease in apparent mass now becomes an increase, and vice versa.
Explanation / Answer
B) It reverses the direction of the force vector on the magnet.
A decrease in apparent mass now becomes an increase, and vice versa. The magnitude of the apparent change in mass is unaffected, but the sign is reversed.
