  • Pete, The word you are looking for in the Amorphous ferromagnetic material. Usually they are heat treated and crystallized to attain a µ in the range of 20K-100K. The toroid is wound using a metal tape with an epoxy insulating layer between the winds to minimize eddy current losses. Great video, inductors are a lot of fun.
