Praxis 5511 Practice Test Practice Question
A bar magnet has two magnetic poles, a north pole at one end and a south pole at the other end. If the magnet were cut in half, which of the following would describe the magnetic poles of the resulting two pieces?
Correct Answer: B
Rationale: When a bar magnet is cut in half, each resulting piece becomes a smaller magnet with both a north and a south pole. This phenomenon occurs because magnetic poles are not isolated; they always exist in pairs.
Option A is incorrect as cutting the magnet does not produce isolated poles. Option C suggests that one piece would lack poles, which contradicts the fundamental nature of magnets. Option D is also wrong; both pieces retain their magnetic properties. Thus, after cutting, each piece will exhibit a north and a south pole, confirming that both halves maintain their magnetic characteristics.
