Abstract
A magnetic film assembly includes a coil having a plurality of turns defining a first major boundary surface of the coil, such that when energized, the coil generates an in-plane magnetic field component in a region of interest in air proximate and substantially parallel to the first major boundary surface, the in-plane magnetic field component having a magnetic field strength H that varies between a maximum Hmax and about 10% of Hmax in the region of interest in air; and a magnetic layer disposed on the coil so as to include the region of interest, such that when energized, the coil generates a magnetic field inducing an in-plane magnetic flux density B in the magnetic layer in the region of interest that varies less than about 5% in the region of interest.
