===== Description =====

An engine that utilizes the Curie point

===== Purpose =====


To demonstrate the effect of raising a material's temperature past the Curie point  



===== Apparatus =====


Curie point engine (comes as a unit) 
Propane torch
Flathead screw driver   



===== Setup =====


1. Insert the propane torch into the slot on the side of the mount as shown (lines on the torch mark the gap) 
2. Ensure the stand is the correct position as shown in the images 
3. The pendulum should be attracted to the magnet stack and should be slightly past the torch 
4. Open the torch valve slightly and light it with a match 
5. Once the magnets on the pendulum are heated past the Curie point the pendulum will swing away from the stack 
6. When the magnets cool down, they will be attracted to the stack again, thereby starting the engine cycle     



===== Notes =====


Height and position of the magnet stack can be adjusted for optimal performance 
Currently the engine is running very slow (15 seconds per cycle)
