Imagine you're packing for the trip of a lifetime: Antarctica! You're going to see the South Pole and maybe hang out with some penguins. But how are you going to find the actual South Pole?

You might think that you would reach for a compass first. Compasses — navigation instruments that contain magnetized pointers — have helped people find their way around Earth for thousands of years. The planet's magnetic field attracts one end of the compass's magnetic pointer toward the North Pole, so compass users always know which way magnetic north lies.
