Herein, we report a new ‘programmable’ responsive shaping behavior induced by the visible multi-dimensional gradient of magnetic nanoparticles (MNP): the materials exhibit different local curvatures and a sequence of responsive shapes during the responsive process; the sequence and the local curvature are accurately defined by ‘programmed instructions’—MNP gradients in the materials.
