Many years ago the earth grew bored at looking at the same dark, night sky day in and day out. It absolutely hated when it would get dark; there was no longer beautiful sunshine to gaze at, and no more breathtaking sunsets. All this was replaced by complete darkness and the faint light of the moon.
One night the earth decided to play with its magnetic force feild. See, the earth had hidden magnetic field lines that went into and out of its magnetic foles. Where the lines where closest together, the field was the strongest. And this caused a strange acceleration in the electrons that surrounded the field.
This all caused the sun to wake up and want to join in on the fun! So the sun sent its magnetic field to play with earth field, it is called solar wind.
But, the solar wind played way to rough. It began pushing earth magnetosphere, where the field is compressed.
This created, an electric charge with an extremely high voltage! The earth had never experienced this before! It was too much for it to handle!
As the Earth began to panic, out came beautiful neon lights of different colors against the night sky! It was the most beautiful thing the earth had ever seen! It named it Aurora. so, now when the earth gets bored it plays with magnetism to see its pretty aurora
