How Magnets Work
The gist
Magnets work because of the alignment of tiny magnetic fields created by electrons spinning inside atoms, which produces a magnetic force that can attract or repel certain materials.
Explain like I'm 5
Imagine lots of tiny spinning tops inside a magnet all pointing the same way, and that makes the magnet pull things like iron towards it, kind of like an invisible hand.
Big picture
Understanding magnets helps us with many technologies like electric motors, generators, and data storage, making magnets essential in everyday devices and industrial machines.
