Magnets are Cool!

"Did you know that the magnetosphere of the earth is about to be turned upside down? The magnetic field of the earth has become weaker and weaker since we started recording it's power in the late 19th century. 10% less.
Lot's of scientist believe this is a sign of a turning of the earth's magnetosphere. The north pole will be the south pole and vice versa. It has happened before, many times. But the last one was 780.000 years ago. The next one is statistically way overtime now. I don't know if this is true, but I took a look at magic and tried to figure out what I can do, with a weakening magnetic field. This it what I have come up with!"

With such introduction you can be sure that people will watch the next effect. So any sort of animated effect could work. Just saying!
