Sharaxaad Gaaban:

Dareemaha u dhowaanshaha magnetic waxaa ka mid ah furayaasha u dhowaanshaha hadda jira, furayaasha u dhowaanshaha awoodda, furayaasha u dhowaanshaha Hall, furayaasha u dhowaanshaha korantada, furayaasha u dhowaanshaha pyroelectric, furayaasha magnetic TCK iyo furayaasha kale ee u dhow. Sababtoo ah dareemaha barokaca waxaa loo samayn karaa iyada oo loo eegayo mabaadi'o kala duwan iyo habab kala duwan, iyo dareemayaasha kala duwan ee barokaca waxay leeyihiin habab "aragti" kala duwan oo shayga ah, waxaa jira dhowr wareegyo dhow oo caadi ah: eddy current proximity switches
