The ends of a magnet are referred to as "poles." Each magnet has two poles: a north pole and a south pole. These poles are critical in understanding the behavior of magnets. The north pole is defined as the end of the magnet that points towards the Earth's geographic north when freely suspended. Conversely, the south pole is the opposite end. The interaction between the poles is fundamental to magnetic forces; like poles repel each other, while opposite poles attract. This property underlies many applications of magnets in technology and mechanical systems, such as motors and generators.

The other terms do not accurately describe the specific ends of a magnet. "Ends" is too general and doesn't convey the distinct magnetic properties associated with each end. "Fields" refers to the magnetic field generated by the magnet, which surrounds it and is influenced by the poles, but does not describe the ends themselves. "Outlets" is not relevant in the context of magnet terminology. Understanding the concept of poles is essential for anyone studying agricultural technology and mechanical systems, as it forms the basis for working with magnetic devices and systems in various applications.
