Temperature effect on magnetism.
The curie point for mild steel is about 750deg C. Before this temp it is ferromagnetic and after that temp its paramagnetic i think. But my question is does the magnet permiabilty of the mild steel gradualy reduce as it gets hotter up to that temp?
If we say Mild steel permiability is 100% at 20deg C what percentage would it be at say 400deg 500deg 600deg...
Is there a graph we can plot that show this? or is it 100% up to749Deg and then suddenly bang its not?
Hope you can help
