Many hints and diagram. A Canadian nickel is attracted to a magnet until it is heated with a torch. 5G50.20 thermomagnetic motor PIRA 1000 5G50.20 thermomagnetic motor 32-3.22 Local heating of permalloy tape or nickel rings in a magnetic field will cause rotation. The rim of a wheel of Monel tape is placed in the gap of a magnet and heat is applied to one side to make the wheel turn. 5G50.20 magnetic heat motor E-110 A thin strip of magnetic alloy around the rim of a well balanced wheel is placed in the gap of a magnet with a light focused on a point just above the magnet.
Heating changes the magnetic properties and the wheel rotates.
A rim of nickel on a wheel is heated just above the point where the rim passes through the gap of a magnet. A gadolinium strip forming the rim of a plexiglass wheel is heated and cooled on opposite sides of a magnetic field, and a weight is lifted by the resulting rotation. A soft iron disk heated on an edge turns very slowly when a magnet is oriented correctly. Use the Curie point engine as a simple demonstration of the Carnot principle. A piece of dysprosium is attracted to a magnet when cooled to liquid nitrogen temperatures but drops away when it warms up.
