A student puts object X on a balance. The student then brings magnet Y near object X, followed by magnet Z, and notes the balance readings. The gap between Y and X is the same as the gap between Z and X. The diagram displays the outcomes of the experiment. Which statement accounts for the results?
- AObject X is an iron block and magnet Y is stronger than magnet Z.
- BObject X is an iron block and magnet Y is weaker than magnet Z.
- CObject X is a permanent magnet and magnet Y is stronger than magnet Z.
- DObject X is a permanent magnet and magnet Y is weaker than magnet Z.
