Magnetoactive liquid-solid phase transitional matter:
Figure 3H presents a cooperative task of object manipulation to demonstrate the splitting and merging ability of MPTM in the liquid phase and the ability to achieve controlled motion and support high load capacity in the solid phase. A liquid MPTM was split into two smaller ones, which then transitioned into the solid phase. These two solid MPTMs applied a torque to rotate a rod by 90° anticlockwise and then pushed the rod to move forward by 14 mm. Finally, these solid MPTMs transitioned back to the liquid phase and merged to form the original droplet.
