Abstract
A magnetic film includes a plurality of magnetically permeable particles dispersed between opposing first and second major surfaces of the magnetic film. The first and second major surfaces are spaced apart a distance D. The particles are agglomerated so as to form a plurality of substantially continuous layers of particles generally extending along orthogonal first and second directions and arranged along a third direction. Each substantially continuous layer of particles has a length L along the first direction from a first to an opposing second edge of the magnetic film and a width W along the second direction extending from the first to the second major surface. L/D≥100.
