Experience the power of magnetism in How It Works Issue 77

Magnetism is a truly incredible force. We have known about it for thousands of years, but only recently have we been able to understand its full range of properties and uses, on our planet and beyond. This amazing invisible force protects Earth, and has given rise to a huge array of important inventions. Without it, we would have no navigation, no radar, no music and no electricity; everything would be very different if we hadn’t figured out how to use them.

Although it was once believed to be a form of magic magnetism is very real, and understanding it’s properties and how it works will help you better understand everyday objects. Join us in celebrating magnetism in issue 77, it really is one of the science’s many wonders.
