Praxis 5511 Practice Question
If a bar magnet is cut in half, each piece has ____.
Correct Answer: B
Rationale: When a bar magnet is cut in half, each resulting piece becomes a smaller magnet with its own north and south poles. This occurs because the magnetic domains within the material realign, ensuring that both halves maintain their magnetic properties.
Option A is incorrect as neither piece can exist with only a north or south pole; both are formed. Option C is misleading because both halves will have poles, contrary to the implication that one would lack them. Option D is also incorrect, as it suggests that cutting the magnet eliminates its magnetic properties, which is not the case. Each piece retains its full magnetism.
