This almost feels like magic. A ferromagnetic alloy made from to non-magnetic metals!
"Bismanol" is an alloy of Bismuth and Manganese, developed in the 1950s by the Naval Ordnance Lab (as hinted to by the -nol in the name).
To make it, I melted 32.9g of Bi and then added 7.0g of Mn to the melt. The mixture was heated to ~800°C and then poured into a mold.
The ratio or the quenching might not be optimal to reach maximum magnetism, but I am pretty pleased with the result.
