Final answer:
A bar magnet is a dipole and thus has two magnetic poles: a north pole and a south pole.
Step-by-step explanation:
A bar magnet has two poles: a north pole and a south pole, making it dipolar. Despite being divided into smaller pieces, each piece will continue to have a north and a south pole. This characteristic demonstrates that bar magnets are magnetic dipoles and do not exist as monopoles, which would be a magnet with only one pole. Magnets align with Earth's magnetic field, allowing a freely suspended magnet to point toward the geographic North and South Poles.
All magnets have two poles: a north pole and a south pole. When you cut a bar magnet in half, each half will have a north pole and a south pole. The concept of a magnetic dipole, which means having two opposite poles, applies at all scales from the atomic level to larger objects.
