1. Ukwahlulahlula: iminyango yeminyango yesiqhelo yemagnethi yohlulwe ngokwendidi enyusiweyo eludongeni kunye nomgangatho onyusiweyo ngokomgangatho ngohlobo lofakelo, uhlobo lweplastiki kunye nohlobo lwesinyithi ngokwento leyo; iijamu zeminyango ye-electromagnetic zahlulwe zaziintlobo ezahlukeneyo. Iimveliso zokufakelwa zahlulwe zangamacandelo amathathu: uhlobo lodonga, uhlobo lomhlaba kunye nohlobo lwetyathanga. Ngokwezakhiwo ezahlukeneyo, uhlobo lodonga lokumisa ucango lwe-electromagnetic luhlulwe lwaba luhlobo oluqhelekileyo, uhlobo olwandisiweyo, uhlobo olwandisiweyo, uhlobo lwebhokisi, uhlobo olufihliweyo kunye nohlobo olude lwengalo.

Uhlobo lomhlaba lokumisa ucango lwe-electromagnetic umnyango luqulathe uhlobo lodonga lokumisa ucango lwe-electromagnetic kunye ne-bracket ye-angle engaphantsi komhlaba; Uhlobo lokumisa ucango lombane wombane luqulathe uhlobo lodonga lokumisa ucango lombane kunye nesivingco sokuqinisa; kuba imizimba ephambili yohlobo lwodonga, uhlobo lomhlaba kunye nohlobo lwetyathiki lokumisa ucango lombane ziqhelekile omnye komnye, kulungele ukuba abasebenzisi bakhethe ngokwemiqathango yofakelo lwesiza.

2. Izinto eziphathekayo: uninzi lweejamu zomnyango ezikumgangatho ophezulu zenziwe ngentsimbi engenasici. Iminyango yeminyango eyenziwe ngezi zinto yomelele kwaye akukho lula ukuyiphelisa. Xa uthenga iimveliso zokumisa ucango, kufuneka sinike ingqwalaselo eyodwa kwinkangeleko kunye nokumila kwescango, itekhnoloji yokuvelisa kunye nobungqingqwa bokutsalwa kwentwasahlobo, kwaye sizame ukuthenga iimveliso ezinobume be-compact, itekhnoloji entle kunye nokuqina okuphezulu .
