NASA | Magnetometry 101

The video tutorial explains how magnetic fields can be visualized using a compass and iron filings. It describes how NASA scientists use magnetometers on satellites to study planetary magnetic fields, revealing insights about planets like Jupiter and Mars. The tutorial highlights that while some planets have magnetic fields similar to Earth's, others like Mars do not. The sun also has a magnetic field affecting the solar system. Despite advanced technology, these discoveries are made using tools akin to an upgraded compass.
