If you take a piece of wood and put it next to another piece of wood... nothing happens.And if you take a piece of granite and put it next to another rock... still nothing.But if you take this piece of iron and put it next to this other piece of iron... magic!I mean, magnet.Magnetic objects are able to magically attract at long distance because they generate magneticfields that extend invisibly out beyond the object. But the mystery is this: where domagnetic fields come from?Derek: well that's easy, Henry! We've known for a long time that electricity and magnetismare really just two sides of the same coin, kind of like mass and energy or time and space,and they can be transformed into each other. In fact, magnetic fields are basically justwhat electric ...
