Fig. S3. An experiment for evaluating the achievable \(\left|\vec{M}\right|\) of the proposed MMR. (A) The dimensions and net magnetic moment, \(\vec{m}_{sp}\), of the molded cuboid samples. (B) A free-body diagram analysis for this experiment. (C) The deduced \(\frac{Wr_{0}\cos\Gamma}{V_{\text{sp}}\sin\varnothing}\) was plotted against the magnitude of the applied magnetic fields (\(\left|\vec{B}\right|\)). Each data point had five trials and the error bars of the data points represented the standard deviation of these points. The best fit line of this graph was constrained to intersect the origin, and its gradient represented the MMR’s achievable \(\left|\vec{M}\right|\). The gradient of this best fit line was computed to be 9.40×104 A m-1.
