How does a magnetic compass work? Well, it’s all down to basic physics and human ingenuity. The key component of a standard baseplate compass is its magnetized needle, which is allowed to spin freely ...

In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...

"As the magma cooled to form what is today the world's solid outer crust, magnetism was locked into minerals containing iron, such as magnetite." When you purchase through links on our site, we may ...
