Was wondering if people had any comments on the safe handling of a toroidal power transformer ferrite core (MnZn PC40)

Right now I'm just going off of this https://www.ferroxcube.com/upload/media/about/En_Sa/MSDS%20MnZn-ferrite_2015.pdf

Apparently it just says don't breathe in any of the dust from it is there is any, and to handle with gloves and basically that its a skin and eye irritant but inhaling any of the dust from it can be bad...

Basically the core I bought isn't wrapped in anything so its just MnZn, does anyone have suggestions on something thats thin that I can wrap it in to make it simpler to handle for when I wind the coil onto it?

This should be safer to work with right? It says N2 Black Coated, same material as the one above.

Should work nicely.  Is the size about what you want?

Its good enough for now for testing... bigger might be better though.

Also I'm a moron that N2 was referring to its inductance value... lol

Only info on the coating was its "black coated" with what idk... some kind of thick shiny paint it seems like..

I put one full wind around it and got pretty much the results I was expecting from the pole interactions of it to another permanent magnet but I need to put another wind or 2 on it to really get it to do what I wanted, and that's with a D cell battery hooked up to it...
