Hey. I`m going to do an experiment to se if the magnetic field around a magnet changes when the temperature of the magnet changes.
According to Currie´s law, M = C x ( B / T ), the magnetization of a material is inversely proportional to the temperature.
If I have understood this right this means that f.ex. a iron nail in a magnetic field will be less magnetized if the temperature of the nail is higher. This equation does not speak of the temperature of the magnet which is making the magnetic field.
My question is: can i use the same equation to determine how the magnetic field around a permanent magnet will change as a function of the magnet´s temperature?
