Ionic liquid at room temperature is a kind of burgeoning green environmental protec- tive material with wide range at liquid temperature, less volatility, good electrical and light conductivity. In recent years as a good fluid medium, ionic liquid at room temperature has been applied vigorously in the field of energy equipments, optoelectronics, microfluidic optical de- vices and so on. The driver of ionic liquid is a new technology in the microfluidic optical appli- cation. This paper presents a method of electromagnetic drive on ionic liquid, with no mechani- cal moving devices, capable of bidirectional drive, and having good stability. The driving speed of the electromagnetic field on ion liquid is measured and compared with the theoretical values in the designed experiment
