Magnetic Flux Guides by Material Extrusion

Advanced Science, EarlyView.
Magnetic flux guidance can increase inductive coupling and forces for magnetic sensors, actuators, and transducers. Here, a magnetic material extrusion method is used to fabricate flux concentration structures of arbitrary shapes with a magnetic permeability of 42. In line with simulation analysis, experimental results show that these materials provide
