PLEASE REQUEST DEMOS WELL IN ADVANCE
Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

video - Magnetic Fields w/ Matrix of Iron RodsPurpose:To show different field patterns.Procedure:  Place plastic plate matrix of iron rods on an overhead projector and place different magnets on top of the apparatus. The iron rods will align with the magnetic field lines. A broken magnet may be used to show that a magnet will always have two poles, regardless how many time it is split in half. NOTE: for the matrix with the mini dipole "arrows", the arrows are not necessarily all magnetized in the same direction. Hints:An alternative set up with larger interacting magnets (see second picture) is available but ordinarily is not part of the main demo.Equipment:
