Someone told me ,that you need the magnets to DE Magnetizing before [charging ]
.
How do you do that ,And is it neccessary ???
Thanks for your Answer .

This might be a some do and some don't situation. If you hold a magnet suspended from a string over the poles, power the charger on, the magnet will rotate to correct orientation which is how I plan on doing it.
I just did a quick search and there are a number of demagnetizers including for 220 line voltage. The prices seem to go from less the $100 USD plus shipping to over $1000. Type demagnetizer into your search box.

I don’t demagnetize them before charging. I rely on its original polarity to align to charger. I do not know of any reason you would want or need to demagnetize them first.
Just measure the strength before and after so you know you increased its field.

I agree with David - I attempt to charge to the same orientation.

Another vote for David. Orientation is simple. Why complicate?

My testing has shown that $100. is a lot to pay for something that is not necessary.
