When magnetized objects orient themselves to point north, this polarity is called?

• A. Normal Polarity
• B. Reversed Polarity
• C. Magnetic Inclination
• D. Pole Reversal

Answer: (A)

The main idea is how the Earth's magnetic field is oriented and how that affects where a magnetized needle points. When a compass aligns to point toward geographic north, the magnetic field direction matches what we observe today in most of Earth’s history. That orientation is called normal polarity. In normal polarity, the field lines exit near the Earth’s geographic north and enter near the geographic south, so the north end of a compass needle is drawn toward geographic north. Reversed polarity would mean the field is flipped, causing the needle to point south. Magnetic inclination refers to how steeply the field lines tilt relative to the ground, not which way the compass points. Pole reversal describes the process of the field flipping over geological time, not the current direction. So the best answer is normal polarity.
