Manufacturing processes yielding stronger, yet cheaper structures are sought for in many industries and scientific application. Freeze casting is a fabrication process that offers a way to achieve these strong, cheap structures, but only in a single direction (the direction of the templating ice growth). Applying a uniform magnetic field to these structures allows one to achieve increased strength in an additional direction. A Helmholtz coil was used to apply weak, uniform fields in a wobbling mode (i.e., a stronger magnetic field in a single direction with a weaker oscillating field in an orthogonal direction) of various magnitudes of wobble during the fabrication of freeze-cast materials. These wobbling magnetic fields led to much more organized as well as stronger freeze-cast materials, compared to freeze cast materials with no magnetic field. These results led to higher performance and cheaper materials.
