The Curie temperature is the point at which materials lose their ferromagnetism and become paramagnetic, requiring an external magnetic field to magnetize. This can have important implications in geology and for magnetic materials used in high heat environments. Data sheets on the properties of ferromagnetic and ferrimagnetic materials discuss their Curie temperatures for reference. The […]
The curie, a unit of radioactivity based on radium, has been replaced by the becquerel in most applications. Radioactivity is measured by disintegrations per second, with one curie equaling 37 billion disintegrations per second. The becquerel is used in the international unit system, with prefixes indicating orders of magnitude. A curie is a unit of […]
