Magnetism

Magnets, those objects that attract or repel each other, are more than staples of your refrigerator door. They are found in just about every laptop and the force they produce protects Earthlings from some lethal radiation from space. Live Science keeps up with the most interesting discoveries related to magnets and magnetism.
