Magnetic Micromanipulation for In Vivo Measurement of Stiffness Heterogeneity and Anisotropy in the Mouse Mandibular Arch
3D magnetic device characterization. (a) Configuration of magnetic poles. Red arrows indicate magnetic flux direction along each pole. (b) Simulated magnetic field under 3 A actuation plotted in ,, and planes as shown in (a). (c) Simulated magnetic field along ,, and axes as shown in (a). The two vertical dash lines indicate a linear magnetic field in the axis (i.e., uniform magnetic field gradient). (d) Linear fitting result of the region shown in (c). (e) Uniform magnetic field gradient workspace. (f) Experimentally characterized magnetic force-driving current data. Error bars represent s.d.
