Akā, he conductive ke kumuhana a kūpono wale no ka ʻike ʻana i nā hemahema o ka ʻili metala; ʻo ka hohonu o ka ʻike ʻana a me ka ʻike ʻike he kūʻē. Ke alakaʻi nei i ka ET ma kahi mea, pono ia e noʻonoʻo piha e like me ka mea, ka ʻāina a me ka maʻamau nānā, a laila e hoʻoholo i ka hoʻolālā ʻike a me nā ʻenehana ʻenehana; ke hoʻohana ʻia ka through-coil no ET, ʻaʻole hiki ke hoʻoholo i ke kūlana kikoʻī ma ka pōʻai o ka hemahema; paʻakikī ka ʻike ʻana i nā specimens me nā ʻano paʻakikī

Hoʻokuʻu ʻia ʻo Magnetic Flux Leakage

E like me Eddy Current, ʻaʻohe nui o ka reuqirement e pili ana i ka maikaʻi o ka surfact, a ʻo ka hōʻailona ʻike ʻia he hōʻailona uila, hiki ke hoʻohana ʻia i nā kikohoʻe e hoʻomaʻamaʻa i ka mālama ʻana, ka hana hou ʻana a me ka hoʻohālikelike ʻikepili a me ka hana ʻana.
