We＊re going to look at magnets for a bit. The Physics Kahuna is absolutely convinced that all of his advanced students no exactly what a magnet is. No mystery here, you have got to be familiar with magnets. First of all, magnets are cool. You＊ve probably had a magnet or two in your young life. There＊s something wonderful about the way they can defy gravity and exert forces on things over distance. The Physics Kahuna would be willing to bet several shekels that you did a magnet experiment or two in grade school. Typical kind of thing would be to try and discover what kind of materials are attracted to magnets; steel screw 每 yes, wooden toothpick 每 no, penny 每 no, quarter 每 no, washer 每 yes, paperclip 每 yes, and so on.
If your elementary teachers were really good, you did the experiment where you put a piece of paper over a magnet and then sprinkled iron filings all around the magnet. The filings line up and make very interesting patterns.
Perhaps you learned to make a compass from a needle.

It turns out that magnets and magnetism are extremely important in modern life. Electric motors, TV＊s, computers, electric generators, locomotives, CD players, all depend upon . . . well, you get the idea.
The first person to write about and study magnets was Thales about 2600 years ago. This is the same guy who looked into static electricity with the amber, remember? Thales found that rocks from a town called Magnesia could attract bits of iron. He called the things, ho mangetes lithos which means the Magnesian rock. This is how the magnet got its name, from good old Magnesia (don＊t confuse magnets from magnesia with Milk of Magnesia, which is a laxative).
Here＊s your basic important circumstance --- magnetism and electricity are very closely connected 每 they are the two sides of a single coin, electromagnetism. So it＊s interesting that one dude, Thales, was the first to study both of these two phenomena.
