Magnetic Field Interaction
Quick fact
The Earth’s magnetic field is constantly interacting with the solar wind, creating the auroras—a visible, large-scale magnetic field interaction happening all the time above our heads.
Why this is interesting
You’ve felt the invisible push or pull between two magnets—but what is actually happening in the space between them? This mysterious force is the result of magnetic fields interacting, and it shapes everything from compass needles to the core of our planet.
