Determination of the Magnetic Viscosity for Cold-Rolled Carbon-Steel 55-Gallon Drums in Earth's Magnetic Field

Containers that are used to transport hazardous waste are usually drums constructed of cold-rolled carbon steel with a volume of 55 gallons. During the drum manufacturing process, the annealing, extruding, and cold rolling of the steel into sheets exerts stresses on the steel’s microstructure which destroy pinning sites between magnetic domains, allowing these domains to rotate and elongate with less required energy, resulting in magnetically softer steel.
