What is the difference between the north pole and the south pole of a magnet?
Which surface?
What is the magnetic moment?
Could you try to explain it better?
My textbook does not have any information about that. Unfortunely, the portuguese high school physics teaching is very poor. That's my opinion. But I will google for Ampere's Law and Biot-Savart. Thank you very much for your help.Tide said:Look up "Ampere's Law" and "Biot-Savart" in your textbook. :)

The North and South Poles are the two points on Earth's surface that mark the northernmost and southernmost ends of the Earth's axis of rotation. The North Pole is located in the Arctic Ocean, while the South Pole is located in Antarctica.
One of the main differences between the North and South Poles is their geographic location. The North Pole is located in the Arctic, which is a frozen ocean surrounded by land masses. The South Pole, on the other hand, is located on a continent, Antarctica, which is completely covered in ice. Another difference is the climate - the North Pole experiences colder temperatures and shorter days due to its location within the Arctic Circle, while the South Pole experiences extreme cold and darkness during its long polar night.
The North and South Poles play a crucial role in regulating the Earth's climate. The polar regions receive less sunlight due to the tilt of the Earth's axis, causing them to be colder than other areas. This creates a temperature difference that drives atmospheric and oceanic circulation, influencing weather patterns around the world. The polar ice caps also reflect sunlight, helping to regulate the Earth's overall temperature.
The North and South Poles are home to a variety of animals that have adapted to the extreme conditions. Some of the animals that can be found at the North Pole include polar bears, arctic foxes, and arctic hares. The South Pole is home to animals such as penguins, seals, and seabirds. Many of these animals have thick fur or blubber to keep them warm, and some have special adaptations such as webbed feet for swimming in icy waters.
The North and South Poles have undergone significant changes over time, particularly in recent decades due to climate change. The Arctic sea ice has been shrinking at a rapid rate, while the Antarctic ice sheet has been losing mass. These changes have had a significant impact on the polar ecosystems and have raised concerns about the future of the Earth's climate. Scientists continue to monitor and study these changes to better understand their causes and potential consequences.
