Iron line orientation inside the PDMS matrix. Iron line orientation inside the PDMS matrix. (A) Micro-CT reconstruction of the polymer/iron mix. The iron lines aligned with the magnetic field direction during the polymer curing. (B) Iron line direction versus position. The direction of the iron lines followed the curing magnetic field direction. Antoine Barbot et al. Sci.
