Variable Outer Radius Individually Addressable Coil Stacks (VORIACS) utilizes concentric three coils per coil-unit-set to exert strong magnetic forces and to articulate the magnetic fields within a compact footprint. This electromagnetic actuation system is utilized for successfully actuating a magnetic clinical needle for difficult-to-penetrate 2% agarose gel.
