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)

That’s correct!

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.

Really? If have had good results just placing a screwdriver inside an electromagnet, still magnetized a few years later.

Maybe it depends on the coil/power source. When I tried it I was just messing around with a coil I had and 12v source and it was not that effective.

I've had good results discharging a 450V 1kJ capacitor bank through several turns of 10 AWG wire. If you don't have a capacitor bank laying around, one of those magnetizers will work just as well.
