I know the properties of a permanent magnet change with temperature and that different magnetic materials have different temperature coefficients. If a permanent magnet has a temperature gradient across its length (i.e one end of the magnet is at a different temperature to the other), which temperature will the properties of the magnet correspond to? Will it act as if the entire temperature is the same as the lowest temperature end, the highest temperature end, or something in between (the mean temperature perhaps?)? Or is it more complex than being able to estimate its properties to a single temperature?
