Question

1. the drawing below is of three separate bar magnets. the north and south poles of each magnet are labeled.

magnet x
n s
magnet y
n s
magnet z
n s
which arrangement shows that the three magnets would attract one another, end to end?
a. magnet x s n magnet y s n magnet z n s
b. magnet x n s magnet y n s magnet z n s
c. magnet x n s magnet y s n magnet z n s
d. magnet x n s magnet y s n magnet z s n

Explanation:

Magnetic attraction occurs between opposite poles (north-south or south-north). We need to check which arrangement has adjacent opposite poles between all three magnets end-to-end:

• Option A: Magnet X (N) faces Magnet Y (S) (attract), but Magnet Y (N) faces Magnet Z (N) (repel) → invalid.
• Option B: Magnet X (S) faces Magnet Y (N) (repel), Magnet Y (S) faces Magnet Z (N) (repel) → invalid.
• Option C: Magnet X (S) faces Magnet Y (S) (repel), Magnet Y (N) faces Magnet Z (N) (repel) → invalid.
• Option D: Magnet X (S) faces Magnet Y (S) is not the case: Magnet X (S) faces Magnet Y (N) (attract), Magnet Y (N) faces Magnet Z (S) (attract) → all adjacent ends attract.

Answer:

D. Magnet X: N S, Magnet Y: S N, Magnet Z: S N
