Question

a magnet placed against the wall of a metal shed falls to the ground, where it attracts a nail. what is the most likely explanation for this observation?
the wall is the opposite pole from the magnet.
the shed is not made of iron or steel.
the magnet is not magnetized.
the nail pulled the magnet to the ground.

Explanation:

To solve this, we analyze each option:

• Option 1: If the wall were the opposite pole, the magnet would stick, not fall. Eliminate.
• Option 2: Magnets attract ferromagnetic materials like iron/steel. If the shed isn’t made of these, the magnet won’t stick to the wall (so falls) but can still attract a nail (since nails are typically iron/steel). This fits.
• Option 3: The magnet attracts a nail, so it must be magnetized. Eliminate.
• Option 4: The nail is on the ground, so it can’t pull the magnet down before the magnet reaches the ground. Eliminate.

Answer:

B. The shed is not made of iron or steel.
