Magnetic film

A magnetic film comprising a plurality of magnetically permeable particles dispersed between opposing first and second major surfaces of the magnetic film spaced apart a distance D, the particles 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 having 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,

• wherein for at least one layer of the plurality of substantially continuous layers of particles, the particles of the layer are agglomerated within the layer such that the layer has a thickness along a fourth direction orthogonal to the first and second directions that is smaller near the first major surface and larger near the second major surface.
