在磁场强度达5 T的条件下制备的琼脂糖凝胶和甲基纤维素凝胶的熔化温度随磁场强度的增加而增加。在凝胶化过程中暴露于磁场导致琼脂糖凝胶中的熔融温度增加（对于0.2wt%凝胶为+1.0K），而甲基纤维素凝胶中的熔融温度降低（对于0.4wt%凝胶为-3.5K）。熔融温度的变化随聚合物浓度的增加而减小，并且在低于3 T的磁场中达到饱和。由于暴露于磁场，构建了稳定的凝胶结构。
The gel-melting temperature was observed for aqueous agarose and aqueous methyl cellulose gels which were prepared under the influence of magnetic fields up to 5 T. The exposure to magnetic fields during gelation caused the melting temperature to increase in the agarose gels (+1.0 K for the 0.2 wt% gel) and to decrease in methyl cellulose gels (-3.5 K for the 0.4 wt% gel). The change in melting temperature was reduced with increasing polymer concentration and was saturated in magnetic fields below 3 T. Stable gel structures were constructed due to the exposure to magnetic fields.
