Each bobble is magnetized in one direction or the other.
It can pre - treat water, there is filter net which has been magnetized in water entrance ( patent no. : 20042000913030 ), it can purify water by absorbing indissoluble and scrap iron in water
對入水進行預處理，在入水口處安裝磁化過濾網（專利號： 2004200913030 ）將水中不溶物及鐵沫吸出凈化了水質。
A non - contact drive and control method on capsule type micro robot was proposed, in which exterior permanent magnet driver was composed of multiple tegular magnetic poles magnetized in radial direction, while interior permanent magnet driver built in robot was in the same structure as exterior one
According to maxwell ' s equations of electromagnetism, as a magnetized object shrinks by a factor of two, its magnetic field strengthens by a factor of four
