The orientation behavior of Euglena gracilis cultures in electromagnetic fields is shown to agree with the predictions of a model involving only a passive mechanism. The increase in Euglena motor activity with increasing field intensity is demonstrated by measuring various motion parameters by the laser scattering technique. The effect of electric field on the speed of Euglenas is compared with that of temperature. We conclude that the electric field warms up the culture, thus inducing an increase in cell motility.

实验表明，纤细裸藻培养物在电磁场中的定向行为与仅涉及被动机制的模型预测相符。通过激光散射技术测量各种运动参数，证实了随着场强增加，裸藻运动活性增强。将电场对裸藻速度的影响与温度的影响进行了比较。我们得出结论，电场使培养物升温，从而导致细胞运动性增加。
