Problem
Two identical bar magnets lie on a straight line with their centers 5 cm apart. Magnet A (on the left) is oriented N–S (its north pole faces right). Magnet B (on the right) is oriented S–N (its south pole faces left). Determine whether the force between the two magnets is attractive or repulsive, and state the direction of the force on Magnet B.Intuitive explanation
The key is to identify which poles are facing each other. Since Magnet A's north pole points right and Magnet B's south pole points left, they face each other across the 5 cm gap. Opposite magnetic poles always attract, so the force between them is attractive—Magnet B experiences a force pulling it to the left, toward Magnet A.
