Ipleyiti egqunywe ngombala ikwabizwa ngokuba yipleyiti yokwambathisa, ipleyiti yentsimbi yombala, isekwe kwikhoyili yentsimbi (ipleyiti eqengqelekayo ebandayo, ipleyiti eshushu, ipleyiti yealuminiyam, ipleyiti ephezulu yealluminiyam, ipleyiti yentsimbi, njl.njl.) njengesiseko semathiriyeli. ukwambathisa umphezulu okanye ukulambisa iintlobo ngeentlobo zezinto eziphilayo okanye ifilimu yeplastiki.Ngenxa yokuba igqityiwe kwi-coil ye-metallurgical surface coil, inokuqhutyelwa ngokuthe ngqo ngabasebenzisi kwiimveliso, ezikwabizwa ngokuba yi-coil yangaphambili.
