Concept:A demagnetized bar magnet has its molecular magnets in random order, so it must be kept away from the Earth’s magnetic influence.
Explanation:The Earth’s magnetic field acts along the North–South direction.
If the freshly demagnetized bar magnet is placed North–South, the Earth’s field can partially realign its molecular magnets.
This would cause the bar magnet to become remagnetized.
Placing it East–West keeps it perpendicular to the Earth’s field.
Thus, no realignment occurs, and the molecular magnets stay randomly arranged.
Answer:A. the molecular magnets remain randomly arranged.
