Magnetism Videos

Some trains these days apply concepts on magnetic fields. Trains can move faster, less prone to wear and tear (less friction) and even not as loud as conventional trains. The following video is about one such train in Japan. The city of Shanghai has its own Maglev (Magnetic Levitation) train a few years back.
Aurora Borealis is a phenomenon when charged particles from outer space are being trapped by the Earth's magnetic field. These trapped charged particles are forced to accelerate along the Earth's magnetic field lines between the magnetic poles. They collide with gas atoms in the atmosphere giving out light.
