PRESENTATION OUTLINE
Earth's magnetic field
earth's magnetic field is generated by a geodynamo, which in earth's case is the iron in the earth's core.

flipping fields!
earths magnetic field is flipping over, due to geodynamo movement patterns

Get to the "point"
compasses are designed with the north side of their magnet to be an arrow

every magnet has a north and south side
opposite sides of magnets attract each 0ther.

prove it!
- place two double sided magnets next to each other
- make sure that the same colors face each other
- one magnets will spin around until the two opposite colors are touching
- this is because the same sides of magnets repell, but the opposite sides attract

picky magnets
magnets only affect certain metals because of the molecular structure, their molecular structure allows the molecules to rotate, which in their turn act like tiny magnets.

electro magnets electromagnets usually have a wire curling around them so that enough energy goes through them at a time to generate a useful magnetic field

maybe the next big thing will be by you!
and maybe you'll use magnetics in the making of it!
