Wound cores made from Mumetal tape

by S. Zurek, Encyclopedia Magnetica, CC-BY-3.0

The trademarked name Mumetal2) was created to denote that this special Ni-Fe alloy exhibits very high permeability.

Similar, the trademarked name Kool-Mu3) (magnetic material made of sintered powder) is related to its high permeability (“mu”) and low magnetic loss (“kool”) exhibiting lower heat dissipation, hence cooler operating temperature for cores with the same size (and the same thermal resistance).
