Detailed explanation-1: -Answer: B) The magnetic pole near the South Pole is a north pole.
Detailed explanation-2: -Which best describes Earth’s magnetic field lines? Answer: ✔ The field lines go out of Earth near the South Pole, enter Earth in the North Pole, and are not aligned with the geographic poles.
Detailed explanation-3: -Furthermore, the magnetic pole near earth’s geographic north pole is actually the south magnetic pole. When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole.
Detailed explanation-4: -The magnetic force can be either attractive or repulsive. If two north poles or two south poles are brought near each other, the force will be repulsive. If a north pole is brought near a south pole, the force will be attractive. The North pole of one magnet is attracted to the south pole of another magnet.
Detailed explanation-5: -Answer and Explanation: According to the definition of the magnetic poles, the north pole of a magnet always attracts the south pole of another magnet and vice-versa.
