• Speakers da headphones: Speakers da headphones suna amfani da magana don kare kulan kula zuwa sauti. A speaker, akwai magana mai tsawo da coil (voice coil) da ke shiga signal na audio. Idan kulan audio ta shiga voice coil, voice coil yana jin-jin a kan amperage force a cikin alamar magana na magana mai tsawo, kuma wannan jin-jinta yana kare zuwa sauti a cikin siffar speaker kamar paper basin. Headphones sun yi aiki mafi girma da speakers, amma su ne kadan da kuma kafin kusa.

• Abubuwan da ake sauki da magana: Hard disk drives (HDDS) masu zamanin sun amfani da magana don sauki abubuwa. A cikin hard disk akwai platters mai duka ta shiga da abincin magana. Abubuwa suna rubuta da karin magana (da ke shiga electromagnets). Magana yana iya gina alamar magana, kara kukan abincin magana a cikin disk don in taimaka wa 0 da 1 na abubuwa.

Tattalin bayanin tattalin arziki da tattalin ranar

• Clamps masu magana da abubuwan da ake raba: A tattalin arziki, magana na magana zai iya amfani a matsayin clamps masu magana don kafa da karamin abubuwan masu magana. Misali, a tashar machining, clamps masu magana suna iya kafa kadan da kuma kasa abubuwan da ake raba a cikin tashar workbench. Abubuwan da ake raba masu magana suna iya raba abubuwan masu magana mai yawa, misali, a tattalin recycling na scrap steel, abubuwan da ake raba masu magana suna iya raba kadan da kuma kasa tonni na steel waste.

• Sensors masu magana: A tattalin otomotif, sensors masu magana suna amfani da su. Misali, speed sensors suna amfani da kisan alamar magana don tabbatar da kisan wheel. A wasu tattalin access control, sensors masu magana suna amfani don tabbatar da tasiri da karamin door, kuma samun detection da transmission an yi a cikin interaction na alamar magana bayan magana da sensor.

• Tattalin lallabi: A tattalin imaging, kamar magnetic resonance imaging (MRI), ana amfani da alamar magana mai yawa da kuma radio frequency pulses don gudanar da nuclei na hydrogen a cikin tashar mutane, sannan tare da karon signals da nuclei na hydrogen suka fara zuwa kare detailed images na tashar mutane.

Dalilin cikakken kuli da aka bani a cikin magana

Akwai lokaci, magana ba su fuskantar kuli ba. Idan kana bani kuli a cikin magana, zai iya kasance gwamnati:

• Reflection of external light: surface na magana yana iya zama smooth da za'a reflect light a cikin environment, misali, a cikin kuli mai yawa, surface na magana yana reflect light kamar mirror, wanda zai iya bani kuli a cikin magana.

• Special optical effects of magnetic materials (less common) : Wasu abincin magana zai iya da optical phenomena masu ma'ana ga kisan alamar magana, kamar magneto-optical effects. Magneto-optical effects sun hada da Faraday rotation effect, inda direction na polarization na light rays yana zama rotate idan suka shiga abincin magana. Idan a cikin wasu device masu bayanai ko abincin magana mai ma'ana, wannan cikakken kuli na magneto-optical effect zai iya bani, amma ba shine nuna na biyu na magana masu tsawo.
