3 method to convert from ferro to parra ? Efforts: 1st: when magnetization remain constant and temperature increases then the magnet will convert from ferro to parra because its field strength decreases. example: the temperature of iron is 770k if it increases from 770k the iron will be converted to parra. 2nd: when temperature is zero and magnetization increases to its maximum. example: ? Question: 3rd: what is the third one? how a magnet could be converted to parra with both magnetization and temperature involving ?
