The word pole has several meanings:

1. A long, thin, rounded piece of wood or metal. A flagpole holds a flag high in the air. A tent pole keeps the tent standing upright. Gymnasts use poles for vaulting, electricians climb utility poles to fix power lines, and firefighters slide down poles to reach their trucks quickly. In the sport of pole vaulting, athletes use a flexible pole to launch themselves over a high bar.
2. Either end of the Earth's axis: the North Pole or South Pole. These are the points farthest north and south on our planet, where it's extremely cold year-round. The North Pole sits in the middle of the Arctic Ocean, covered by shifting ice, while the South Pole sits on the continent of Antarctica, covered by thick ice sheets. Explorers like Roald Amundsen and Robert Peary became famous for reaching these remote, frozen places.
3. The ends of a magnet, battery, or the Earth's magnetic field. Every magnet has a north pole and a south pole. Opposite poles attract each other, while identical poles push each other away. When you connect wires to a battery's positive and negative poles, electricity flows through the circuit.
