1. A method of forming a magnetic assembly having at least one magnetic layer having dimensions of thickness, width and length, and at least one printable substrate layer having dimensions of thickness, width and length, the method comprising the steps of:

  • a) providing a magnetic composition comprising about 70 wt-% to about 95 wt-% of at least one magnetic material and about 5 wt-% to about 30 wt-% of at least one thermoplastic binder;

    b) forming said magnetic composition into said magnetic layer at an elevated temperature; and

    c) directly applying said magnetic layer at an elevated temperature to a first surface of a printable substrate layer; and

    d) providing an adhesion promoting layer between said magnetic layer and said printable substrate layer for promoting adhesion between said magnetic layer and said printable substrate.
