I think that no the strength of magnetic doesn't change in temperature change .

hy.. anx olk so to be precise even if i put a magnet in different temperatures,its strength doesnt change?

Yes, it can but in a very high temperature
, normally the magnetization power of a magnet will Decrease with increase in temperature and if its heated above a point which is called (currie point) then the magnet will be demagnetized as but some magnets can resist upto very high temperature which is not possible in normal conditions, the reason for magnet to lose magnetism here is that when it get heated at high temperature the atoms starts vibrating and it's vibration increases with temperature which causes the interference in magnetic field or
We can say that magnet ends have an opposite charge, or magnetic direction, at each end. This is a result of most of the magnetic molecules facing the same direction. When we heat our magnets, those polar molecules(south pole atoms and North pole atoms) start moving around. The average direction of the entire magnet’s polarity becomes a little bit messier because those magnetic molecules are no longer facing the same direction, which cause the magnetic field to get a bit messier as we know a magnetic field is the force field created by moving charges which gets destroyed as charges (electron) starts vibrating which Decreases the force or it's magnetic power.
NOTE : it only happen in case of permanent magnet, THIS doesn't work on electromagnets

olk anx...m doin a project on the effects of varying temperature on the strength of a magnet
oh so u need to just heat it and observe it
what bout cooling it....isnt tat necessary as well
