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.

Thanks
Albert.

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...
