Nitinol Wire

nitinol wire

Nitinol is a shape memory alloy actuator wires. Its operation resembles that of a muscle; it contracts when heated. Many times an electric current is passed though the wire to heat (ohmic heating) the wire to its transition temperature. When the electric current is removed, it cools and can easily be stretched back it its original length. Nitinol wire is sold in five standard diameters; .006, .008, .010, .012 and .015 dia. Priced provide is per linear foot.

Pyrolytic Graphite Levitation Kit

Click Picture for Video Levitating graphite in dome

Magnets affect materials in one of three ways, attraction, non-attraction (neutral) and replusion. Diamagnetism refers to an objects weak repulsion from an magnetic field. There are no poles connected with diamagnetism. The north pole of a magnet repels the material just as well as the south pole. Just like a north pole of a magnet will attract iron just as well as the south pole. Graphite is diamagnetic. Pyrolytic graphite is 10000X more diamagnet than most common diamagnetic materials such as water. Thin slices of pyrolytic graphite are extremely light and can be made to levitate. The closest thing to a perfect diamagnetic material is a superconductor however superconductors still require liquid nitrogen to become superconductive. Whereas pyrolytic graphite can levitate at room temperature.


LEV-01 Kit includes (4) neodymium magnets, (1) steel base plate (1" x 1" x .036 " thick), (1) Plastic Dome and (1) Pyrolytic Graphite.
