it would lose all magnetic properties at 175 degrees cause when you heat a metallic metal like that, the heat breaks down the lattice that holds the molecules in place, and thereby weakens the forces holding the magnetic domains in a north south pattern, and allows them to scramble up, removing the magnets strength.
So when it cool it would just be a neodinum chunk, with very weak magnetic field strength.
To make it strong again youd have to heat it, and then cool it in the presence of a very strong external magnetic field, so the domains will cool in a magnetic north south pattern
Though I suspect that the fridge door may object to the 175C.
How are you re-magnetizing it again, another one of these I suppose.
