Many people try to solder wire with magnets. But magnets lose its magnetic strength when heated up above 80° C to 100°C. Many suggested to solder quickly and use metal as heat sink.
But here I am showing a way where you can solder wires on magnet without losing its magnetic strength.
But first you need to understand an Atom is a very tiny magnet. In a big magnet they align their magnetic fields in one particular direction. Heat disturb this alignment. Therefore the magnet loose its magnetic strength. When heated above 80° C, a magnet will quickly lose its magnetic properties.
Heat a small magnet in present of a large magnet, which will attracts the tiny magnetic fields, therefore they do not get misaligned. You can always take advantage of using iron metal sheet as heat sink with the above process.
