Extended Data Fig. 3: Micro-computed tomography images of printed fibres.
From: Printing ferromagnetic domains for untethered fast-transforming soft materials
a, A fibre printed with a nozzle of diameter 410 µm in the absence of applied magnetic field. b, A fibre printed with a nozzle of diameter 410 µm in the presence of an applied magnetic field of 50 mT at the nozzle tip. No obvious aggregation of ferromagnetic particles in the printed fibres can be observed.
