Earth’s magnetic field gives us a layer out in space called the magnetosphere. If you want to learn everything about magnetosphere, this is the complete guide.
Charged particles or plasma makes up about 99% of the universe. Magnetic reconnection involves how this plasma interacts with magnetic fields (like Earth’s)
During magnetic storms, trapped plasma flashes lights that are observable around the globe. This disturbance in the magnetosphere is the Aurora Borealis.
The magnetic field gives us a layer out in space called the magnetosphere. Without it, Earth would be exposed to solar and cosmic radiation.
The Earth is a big magnet. This is why compasses point to the magnetic north. But north didn’t always point northward because of magnetic pole reversals.
