Fabrication of soft magnetic carpets. a) Sketches of the fabrication steps of our SMCs, depicting how the magnetic prepolymer forms pillar‐like structures that become stable after being cured at 60 °C. The pillars carry a permanent magnetic dipole moment and therefore respond to external magnetic fields. b) A reconstructed 3D reflection microscopy scan of the SMC; no magnetic field is applied here. c) Reflection microscopy images of the pillars sketched in (a), without an external magnetic field, with an oppositely directed field (compared to the formation), and with a half similarly and half oppositely directed field, respectively. Scale bars are 200 µm.
