One of the things you probably didn't know is that motors use magnets to spin. Now the magnets aren't made of the stone magnets you probably are thinking of. No, they use electricity to generate a magnetic field spinning an axle.

Earth magnet

DId you know that the earth uses magnetic fields to stop solarwinds? Solarwinds are described as “an emanation from the sun's corona consisting of a flow of charged particles, mainly electrons and protons, that interacts with the magnetic field of the earth and other planetary bodies.” (Dictionary.com) The reason that this is important is because if any solar wind passes through the magnetic field, all of the electronics we have will fry.



Magnetism is a very interesting concept, mostly because it's used in so much that you probably didn't know about.
