英文摘要	The invention relates to a method for preparing a carbon nano-tube AFM probe based on an electromagnetic field, which comprises the steps of: establishing a dielectrophoretic force theoretical model of carbon nano-tubes in a solution under an external electric field adjusting the voltage amplitude between the prior AFM probe and a conductive substrate or the gap between the prior AFM probe and the conductive substrate, and controlling the field strength between the prior AFM probe and the conductive substrate imposing an alternating current electric field between the prior AFM probe and theconductive substrate through a waveform signal generator under the monitoring of an optical microscope, dripping the carbon nano-tube solution into the space between the prior AFM probe and the conductive substrate until the tail end of a tip of the prior AFM probe is immersed and keeping the probe stand for 5 to 50 seconds, and then disconnecting an external alternating current signal to finish the preparation. The method has easy control, simple manufacturing conditions and low cost, and has the characteristics of environmental protection, energy conservation and the like.
