Do you mean to use it to magnetize objects?
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.

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.
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.
I appreciate it, I didn’t realize it was so temporary
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.
You will need to feed it with DC.
