TLDR
The effect of microgravity on protein crystal growth is an interesting, but highly controversial, issue as mentioned in this paper, where the magnetic force was used similarly to the centrifugal force in a space shuttle to virtually change the level of gravity and the number of crystals increased or decreased when 5% of the additional force was applied in the same or in the opposite direction to normal gravity.About:

Study on the Effect of Magnetic Fields on Polymeric Materials and Its Application
TL;DR: In this paper, two main magnetic effects on polymers are considered, i.e., alignment and levitation, and examples of alignment in polymeric systems are presented, starting from simple cases such as magnetic alignment of fibers in a suspension to more complicated cases like magnetic alignments of crystalline polymers in which mesophase formations and memory effects are involved.

Crystallization of proteins under an external electric field
TL;DR: In this paper, the effects of an external electric field on the crystallization of hen egg-white lysozyme at 293 K, pH 4.5, and two NaCl concentrations (0.6 − 0.7 M) have been investigated using the vapor diffusion method.

Christo N. Nanev,Anita Penkova +1 more
TL;DR: In this paper, the preferred orientation along c-axis of hen-egg-white lysozyme (HEWL) crystals has been observed in an external electric field, and the HEWL crystals grew predominantly on the cathode side of the glass cell.

Effects of a magnetic field on the nucleation and growth of protein crystals
TL;DR: In this article, the authors used a steady and uniform magnetic field of 10 T and compared with the crystals grown under 0 T. They demonstrated that a magnetic field reduced the number of nuclei and not only oriented the crystals but also modified the habit of protein crystals.

Magnetic orientation as a tool to study the initial stage of crystallization of lysozyme
TL;DR: In this article, the tetragonal crystals of hen egg-white lysozyme align their c-axis in the direction of a magnetic field, and it was found that crystals grew in solution, and started to sediment on reaching a critical size.
