When I was a kid my Dad made a magnet charger with some electrified copper coils would this be something that could be used to achieve similar results somehow? TIA (i.imgur.com)

Putting a tool in a powered coil will magnetize it temporarily but I don't think it will stay magnetic or at least not for long. They sell little magnetizers that you can get cheap that will last a lot longer though if that's what you're looking for..

I have one like this around somewhere that worked well when I tried it.

    Depending on the coils number of windings, and the size of the tool it will magnetise it pretty well. I used to do this to screwdrivers before they came pre-magnetised. And they will stay magnetised for a very long time.

    Most of the time the reason for becoming demagnetised is due to dropping the tool several (many) times.
