Magnetically Levitated Planar Actuator with Moving Magnets [PDF]
2007 IEEE International Electric Machines & Drives Conference, 2007 This paper concerns the design, optimization, and commutation of a six-degree-of-freedom planar actuator with an active magnetic bearing. The planar motor has a stationary coil array and a translator with a Halbach magnet array. During movements in the plane, the set of energized coils changes with the position of the translator.

Magnetic actuation of hair cells [PDF]
Applied Physics Letters, 2011 The bullfrog sacculus contains mechanically sensitive hair cells whose stereociliary bundles oscillate spontaneously when decoupled from the overlying membrane. Steady-state offsets on the resting position of a hair bundle can suppress or modulate this native motility.

Computation of magnetic field in an actuator [PDF]
Simulation Modelling Practice and Theory, 2008 Abstract Design and optimization of an actuators based on magnetostrictive technology requires computation of the magnetic field. The “MS”-technology offers an attractive controllability with high power density. The magnetostriction is a reversible feature which can be used in various actuator layouts.
