Hoʻopiliʻia ka hopena o ka electromagnetic a me Eddy i kēia manawa Inā hele kēia kelepona ma o ka paipu Steel, mai ka pā kīwī,ʻo ke kahua e pili ana i ka piʻipaki marpomagnetic. Hoʻokumuʻia nāʻano o Eddy i ka neʻeʻana o nā electrons manuahi ma kahi pākeke ma lalo o ka mana o kahi pākeke ma keʻano. Hoʻopau kēia kaʻina hana i ka ikaika uila a kumu e kumu ai i ka pipe pila e wela ai. Inā he wela nui, hiki iā ia ke kumu i nā pilikia palekana e like me ke ahi.
Aia ka papa hana magnetic me nāʻaoʻao o keʻano o kekahi i waho: inā he mau'āpana likeʻole ma nā papa hana heʻekolu, ma muli o keʻano heʻelima mau loa ma loko o ka pailaʻekolu. Eia nō naʻe,ʻo ia wale nō e loaʻa i kahi mea hana hoʻokahi-core hoʻokahi wale nō,ʻo ke kahua magnetic a lākou e hiki ai ke kāpaeʻia e nā mea hana'ē aʻe.
