1 Magnetism SWBAT describe how magnets exert forces on each other; explain why some materials are magnetic; describe how objects become temporarily magnetic; explain how an electric generator produces electrical energy

2 Magnets  What are magnetic poles? The ends of the magnet, north and southThe ends of the magnet, north and south N N SSS N

3 Magnetic Fields  How are the attraction and repulsion of magnetic poles similar to the attraction and repulsion of electrically charges? Like charges repel and unlike charges attractLike charges repel and unlike charges attract  Draw the fields you see produces on the overhead examples.

4 Magnetism  Magnetic domain a group of atoms that have their magnetic poles pointing in the same direction.a group of atoms that have their magnetic poles pointing in the same direction.  Electromagnet a current-carrying wire wrapping around an iron corea current-carrying wire wrapping around an iron core  Electromagnetic induction the production of an electric current by moving a magnet and a loop relative to each otherthe production of an electric current by moving a magnet and a loop relative to each other
