Imagnethi eqatywe ngerabha kukusonga umaleko werabha kumphezulu ongaphandle umazibuthe, odla ngokusongwa ngeemagnethi ze-NdFeB ngaphakathi, i-iron eqhuba imagnethi kunye neqokobhe lerabha ngaphandle. Iqokobhe lerabha elomeleleyo linokuqinisekisa imagnethi eqinile, enqabileyo kunye neyonakalisayo ukunqanda umonakalo kunye nokuhlwa. Ilungele ukusetyenziswa kwemagnethi yangaphakathi nangaphandle, njengakwimigangatho yemoto.
