a Dynamic heading error: The spin precession plane adiabatically follows Btot. b Measurement of the probe beam heading error: The solid points represent experimental results, while the dashed lines correspond to theoretical predictions based on the proposed model. c Eddy currents generated by different rotating field alterations: Measurement of the transverse magnetic field (y-axis) induced by eddy currents due to zero-altering and peak-altering modulations. d Eddy Current Time Constant: Measurement of the eddy current time constant during a single panorama measurement of MDA.
