Curie point of magnet
Webdeviation of a magnetic (curie point) transition temperature from the standard reference temperature. The measured deviation can be applied as a correction term to subsequent measurements. In this technique, a curie standard material is placed in an empty, tared TGA pan located near a strong magnet. The material is then heated. WebThe Curie point of ceramic magnets is about 734 K. Alnico Magnets – Alnico magnets have a color like aluminum or sometimes they are coated in red color. The Curie point for these magnets is about 1135 K. …
