The rod amplitude is reproducible across an array, and increasing the actuation frequency results in a minimal decrease in rod amplitude and thus bend angle. (a) Measured amplitudes for eight rods (10 μm length, 550 nm diameter, LNi ≈ 3 μm) as a function of applied magnetic field; magnetic saturation of the Ni tubes begins around 1000 Oe. (b) Rod amplitude as a function of frequency for a low applied magnetic field of 110 Oe. The change in amplitude from the lowest to highest frequency is ~7%.
