If you make love a magnet , rig it liberal . If it comes back to you , it ’s due to a temperature call Curie . search , I ’m not a poet . Just say this .
magnetic attraction requires a level of order of magnitude . A attractor is a piece of music of alloy in which the magnetic moment of its atoms are in line . We’ve talked before about how magnetism and temperature regard each other . enforce a magnetic field of operations on a steady man of metal and , as the order of its magnetic bit increases , the disorderliness of the movement of its molecule increment , get the metallic element to heat up . Heat can also destroy magnetic attraction . We can see the mechanism for this when we look at extreme . A sea of molten metal is not hold up to have neat molecule .
Every alloy has a temperature call aCurie temperature , or Curie point . It is this temperature at which the metal miss its ferromagnetic properties . Ferromagnetism is what you reckon about when you think about a regular , wedge - it - to - your - fridge attractive feature . When heated past the curie point , the metal retain paramagnetism , the ability to respond to a magnetised field , but it ca n’t enforce that magnetic field any longer .
unlike metal have different Curie temperature . Some are high , some are low , and some are uncanny . Gadolinium , a metal that model in the little supplementary incision of element hung below the man periodical tabular array , is an uncanny one . It is ferromagnetic proper at room temperature , butheat it up a little more , and it turn a loss its ferromagnetic belongings . So nibble up gadolinium and bear it in your hot fiddling deal to picture out how magnetism works , and it will stop being a attractive feature .
