Scientists Builds His Own Tiny Planet to Create a Magnetic Field
12:30AM Adam Frucci | Yesterday, I showed you a great video of NASA scientists explaining how magnetic fields work over beautiful animations making the fields come to life. Today, now that you’re all caught up on how the fields work, I’ll show you how geophysicist Dan Lathrop is building a fake planet filled with liquid sodium that will, if all goes according to plan, end up with a magnetic field of its own.
