Concept:A natural magnet such as lodestone aligns itself with the Earth’s magnetic field when freely suspended.Explanation:When a lodestone is suspended freely, it rotates until its magnetic axis points in the general geographic north–south direction.This is because the Earth acts as a giant magnet, attracting the north-seeking pole of the lodestone toward the north and the south-seeking pole toward the south.Therefore, the lodestone points approximately along the N–S line, not east–west or any diagonal direction.Answer:B. N–S when suspended freely
