Hi I have replaced a magnet on aXO3/ XO4 motor, and I now have the spare magnet which still has some magnetism in it. Am I ok to put it with another XO3/XO4 motor magnet that is still on the motor, will it still keep the magnetism it has.

Hi Albert

The best method of storage is to demagnetize it and re-magnetize before using it again.

To demagnetize, make a coil, put the magnet inside and apply an alternating current. (Electrical knowledge is required.) To re-magnetize, use the same coil and apply a direct current.

Is it worth the effort ?

I may be mistaken but I seem to recall from my 'O' Level Physics some 50+ years ago that if you put a weak magnet next to a strong magnet the strong magnet will get weaker and the weak magnet will get stronger until they reach equilibrium.

Not sure on that, I do know that they will stick together, unless they push them selves apart.

I have about five small magnets of different shapes and strengths all stuck together on my bench that I use for various things and they all seem to stay as they were originally...
