MAGNETISM UM Physics Demo Lab 07/2013 Pre-Lab Questions How are magnetic poles similar to electric charges? How are magnetic poles fundamentally different than electric charges? EXPLORATION Materials 1 battery board 1 Petri dish of paper-clips 1 alligator lead card 1 small piece of steel (for scraping off 1 bolt wire insulating enamel) 1 spool of copper wire 1 wooden block (pedestal for compass 2 ceramic Magnets and magnets and wire scraping 1 compass backstop) 1 fur strip Magnetic Forces and Poles The two ceramic magnets are marked with an orange square on one side. On top of the wooden block, place the two magnets a few inches apart, standing on edge with the orange squares facing each other. Move the magnets toward each other and observe how they affect each other. Record your observations below.
