Sharaxaad Gaaban:

Beddelayaasha u dhowaanshaha birlabta waxaa ka mid ah badhanka u dhowaanshaha hadda ee eddy, badhanka u dhowaanshaha awoodda, badhanka u dhowaanshaha hoolka, badhanka u dhowaanshaha sawir-qaadista, badhanka u dhowaanshaha pyroelectric, badhanka magnetic TCK iyo badhanka kale ee u dhowaanshaha. Sababtoo ah dareemaha barokaca waxaa lagu samayn karaa iyadoo la raacayo mabaadi'da kala duwan iyo habab kala duwan, dareemayaasha kala duwan ee barokacana waxay leeyihiin habab "aragti" oo kala duwan oo shayga ah, waxaa jira badhanka u dhowaanshaha ee caadiga ah ee soo socda: badhanka u dhowaanshaha hadda ee eddy Beddelkan waxaa sidoo kale loo yaqaan badhanka u dhowaanshaha inductive. Waa isticmaalka walxaha gudbiya ee u dhow tan waxay abuuri kartaa goob elektromagnetic ah. Nooca
