Electromagnetic Induction leh Eddy Current Effect: Current inthlak danglam chuan -core cable pakhat a paltlang chuan cable vel chu alternating magnetic field a lo chhuak a. He cable hian steel pipe a paltlang chuan, steel pipe chu conductor a nih avangin, alternating magnetic field chuan steel pipe chhungah electromagnetic induction a siam ang a, chutah chuan steel pipe-ah eddy current a siam ang. Eddy currents hi magnetic field in a nghawng hnuaia steel pipe-a free electron circular motion atanga siam a ni. Hetiang hian electrical energy a hmang a, steel pipe chu a lum phah a ni. A lum lutuk chuan kangmei ang chi himna chungchangah harsatna a thlen thei a ni.
Magnetic fields with opposite current directions cancel each other out: Circuit khata cable tam tak (phase line pathum leh neutral line pakhata three{0}}phase four-wire system-a awm ang chi) chu pipe kaltlangin an kal dun a nih chuan, an current direction-a an awm dan kalh avangin, magnetic field siamte chu an in cancel chhuak ang a, chutiang chuan steel current pawimawh tak tak an siam chhuak lo vang. Mahse, single-core cable hian conductor pakhat chauh a neih avangin magnetic field an siam chu conductor dangin an cancel theih loh avangin eddy current effect chu a lang chiang zawk ang.
