Inductor-ka Toroidal waa qaybo dadban oo ka muuqda gariiradda silig dahaaran ama nabar dhalaal leh oo ku yaal qaab donut-qaabaysan oo ka samaysan ferrite ama birta budada ah. Wax ku ool ah oo la isku halayn karo, toroids waxaa loo isticmaalaa naqshadaha wareegga-soo noqnoqda ee hooseeya ee u baahan inductances waaweyn. Waxaa si weyn loogu isticmaalaa caafimaadka, warshadaha, nukliyeerka, alaabta maqalka hawada, darawalka LED iyo ku dallacaadda wireless-ka ee baabuurta,iyo codsiyada kale ee elegtarooniga ah. Haddii nakhshad wareeggu u baahan yahay inductor toroidal oo tayo leh, ka raadi kuwa hormuudka ka ah soo saarayaasha, Future Electronics.
