What your asking is not very clear, but I’m assuming this?
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

Apologies for not being clearer. What I mean to describe is a magnetizer - something that you might put a metal tool through to make it magnetic

Any strong magnet can magnetize other things, depending on the material. Iron can be relatively easily be magnetized, while neodymium magnets require a huge (but obtainable) field.
That looks like a big electromagnet, from a motor, it will probably work, but you have to feed it DC, not AC. (Or else the object will be demagnetized when removed)

Thank you for your insight! I am getting closer!

I magnetize screw drivers with just a normal magnet. What’s your usecase to need such a big magnet?

I just wanted to recreate the device my dad made with me as a kid

Fun stuff

Or you could pick up an iron rod and strike a firehydrant like MacGyver.

Do you mean to use it to magnetize objects?
lossykittens@reddthat.com 1 year ago
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…

You will need to feed it with DC.
