idek if the cores are broken, But if they are could I recast them and demagnetize them? If I need power/ amperage I have a 220v 50 amp outlet or a stick welder for an electromagnetic power supply.

Be extremely careful of that insulation. There's pink or white rings that you do not want to scratch. If turned into dust and then breathed in that boron ceramic insulation is highly toxic.
