In the electromagnetic field that countercurrent inductor produces, the metal droplet that melts gets the role suspension of electromagnetism force in quartz pipe center and had been heated up continuously. When metal droplet of melting have been heated up certain temperature surface beginning gasification, metal vapor tension will raise follow temperature go up, is heated continuously can have plenty of metal atoms overflow metal ball liquid surface, at the same time, as the inert gas of cooling medium, all along with certain current velocity, sideswipe the metal droplet surface that melts. Metal atoms fly out liquid surface according to certain way form the atom cluster by the condensing of inert air current, merger and the collision between crystal nucleus pellet and atom cluster form the smoke flame of nanoparticle pellet eventually.

在逆流感应器产生的电磁场中熔化的金属液滴受电磁力的作用悬浮于石英管中央并继续被加热，当金属熔球被加热到一定温度时表面开始气化，金属蒸气压随温度的升高而升高，继续受热会有大量的金属原子飞出熔球液面，与此同时，作为冷却介质的惰性气体始终以一定的流速掠过熔化的金属液滴表面，原子飞出液面受冷后就按照一定的方式凝聚成原子簇，在惰性气流中形核并随之长大，颗粒、原子簇间的碰撞与合并，最终形成金属纳米颗粒的烟焰。
