    3 method to convert from ferro to parra ?

    when magnetization remain constant and temperature increases then the magnet will convert from ferro to parra because its field strength decreases.
    the temperature of iron is 770k if it increases from 770k the iron will be converted to parra.

    when temperature is zero and magnetization increases to its maximum.
    example: ?

    what is the third one?

    how a magnet could be converted to parra with both magnetization and temperature involving ?
