A write-erase magnet assembly for a data storage device including: a permanent magnet having a longitudinal axis and having a first longitudinally extending face portion with a first polarity and a second longitudinally extending face portion with a second polarity opposite the first polarity for alternately producing write and erase magnetic bias fields on an adjacently positioned data storage medium; a magnet support assembly for rotatably supporting the permanent magnet; a magnetic detent fixedly positioned relative to the longitudinal axis of the permanent magnet for magnetically producing a biasing torque on the magnet tending to orient the closer of the first and second face portions of the permanent magnet in adjacent relationship with the detent. A coil for applying flipping torque and braking torque for an eddy current rotation dampening assembly are also disclosed.
