Magnetic Field Demonstrator

This device is designed to demonstrate the behavior of magnetic fields. For instance, passing a ferrous object like a Coke bottle cap or a small tool across the surface will cause the little magnets to jiggle, while objects such as guitar picks, keys, and American coins, being non-ferrous, will have no effect. Placing a magnet next to the device will cause the little magnets to react according to their magnetic properties. For instance, using a circular magnet will cause the little magnets to arrange themselves in a circular pattern while bar magnets will cause the little magnets to arrange themselves in tightly packed rows. For the more adventurous, iron filings can be sprinkled on the surface of the device, illustrating even more characteristics of the magnetic field. As the magnetic field is a manifestation of the electric field this device also provides an insight into the behavior of charged particles. While it is not an exact representation, the behavior of the little magnets is
