Magnets

Today in class we learned about Magnetic Force. We observed how magnets pull things to them that are metal. Magnets wont stick to hair, plastics  or wood. Magnets have a positively charged core. They can be used in CD players, DVD players, TVS and Computers. You should NEVER put a magnet next to anything electronic. There are North and South Poles on a magnet. Opposites attract! North pole attracts to South pole. If you put North and North together, they push away. Period 7
