Abstract
Inductive elements comprising anisotropic media and biasing coils for magnetically biasing thereof and methods of manufacture and operation for use in applications such as microelectronics. Application of an electrical current through the bias coils generates a magnetic field that biases the magnetic material such that a desirable orientation of anisotropy is achieved throughout the magnetic core and enables modulation of the inductive response of the device. Electrical conductors coupled to interconnects are magnetically coupled to magnetic core layers to produce self and/or mutual inductors.
