  • Magnetic implement using magnetic metal ribbon coated with insulator
    Patent number: 7138188
    Abstract: A magnetic ribbon or sheet is coated with an electrical insulator prior to formation of a magnetic implement. Manufacture of the magnetic implement is accomplished in a single process without a need for co-winding magnetic and insulator ribbons. Thermal property differences between the magnetic material and the insulator operate during heat treatment to enhance magnetic property modification of the implement.
