Beakman builds a DIY compass using a needle and water, shows it in action and then explains the science with a short animation clip. Then there is a song about magnetism. Beakman then explains how the earth acts as a magnet and this is why compasses always point north.
Neil deBuck Weasel and the opossums are happy to find space rocks, which consist of iron, carbon, and a hint of nickel. They soon learn that the rocks have unusually strong magnetic fields and attract to each other. Although largely exaggerated, this clip could be used to illustrate magnetism and the elements found on asteroids.
Sheldon is invited to explain magnetic monopoles to the listeners of the NPR radio channel, and Barry Kripke takes this opportunity to pull a prank on him. Sheldon explains that ordinary magnets have two poles: a north and south. He mentions that cutting a magnet in half would not create a monopole; rather, it would create two smaller magnets, each with its own pole.
