Mà ce Fluxmeter?

Fluxmeter tana da shi?

Bayanin

Fluxmeter ita ce alama da aka fadada don bincike magnetic flux na magnet da ya fi tsauwa. Ita ce babban karfi na ballistic galvanometer, wanda yake da damar muhimmanci. A cikin damar, fluxmeter yana da controlling torque mai kadan da electromagnetic damping mai yawa.

Kunneko na Fluxmeter

Kunneko na fluxmeter ana bayyana a cikin rasa da za a iya gano ta haka. Fluxmeter yana da coil da ake susu ne a kan spring da fili mai kadan. Wannan coil yana iya zo ne a kan magnetic field da ake samu a kan poles na magnet da ya fi tsauwa.

Current yana zama a kan coil karkashin helices. Wannan helices suna da ingantacce mai kadan da suka samu a kan annealed silver strips. Wannan kunneko yana haɗa controlling torque zuwa ma'adin mutum. Kuma air friction damping na coil yana da muhimmanci mai kadan da za a iya ba da shi.

Yadda Ake Amfani Da Fluxmeter

Kamar yadda aka nuna a cikin rasa, terminals na fluxmeter suna da shiga a kan search coil. Magnetic flux na coil yana iya canzawa ta hanyar koyar coil daga magnetic field ko ta hanyar koyar magnetic field na magnet. Wannan canza yana jin emf (electromotive force) a kan coil. Induced emf, kuma yana jawo current a kan search coil, wanda yana zama a kan fluxmeter. Saboda wannan current, pointer na fluxmeter yana zama, kuma yadda ake zama yana da shugaban canzan magnetic flux linkages.

Idan canzan flux linkages yana koyar, coil yana daya zo saboda electromagnetic damping mai yawa. Electromagnetic damping mai yawa yana faru ne saboda low-resistance circuit da ke faru a kan fluxmeter da search coil.

Abubuwan da Fluxmeter Yana Da Su

Fluxmeter yana da abubuwan da su:

• Ita ce portable, wanda yake da shawarar amfani da shi a wurare dabam-dabam.

• Scale na ta ana calibrate a Weber-meters, wanda yake da shawarar maimaita da standard unit of measurement for magnetic flux.

• Zaman zama na coil ba yana da shugaba da lokacin da ake yi canzan flux. Wannan damar yana ba da shawarar measurements masu inganci da kuma inganci, ba tare da rate da magnetic field yake canza ba.

Matsaloli

Matsalolin da ya fi shahara a fluxmeter shine sensitivity da accuracy mai kadan idan ake kula da wasu abubuwan da ke amfani da su don bincike flux.
