Warnings: The True Story of How Science Tamed the Weather by Mike Smith tells the story of our storm warning system. See our online store book collection.

Earth's North Magnetic Pole interactive

This interactive illustrates how a compass is used to find North, and how a compass can give a false reading because the North Magnetic Pole is not in exactly the same place as the Geographic North Pole. Drag the compass around the map to see how well it does at indicating True (Geographic) North.

(Note: If you cannot see the animation below, or it is not working properly, you may need to download the latest Flash player.)
