Faraday’s Law ta Yadda Iya Bani

Faraday’s law of electromagnetic induction (tana da take kiran Faraday’s law) ita ce babban kano na electromagnetism wanda ke nuna yadda magnetic field zai iya tabbatar da electric circuit don bani abu da ya fi sani electromotive force (EMF). Wannan alama tana da sunan electromagnetic induction.

Faraday’s law yana cewa zarafi zai canzawa a conductor wanda ana taka da magnetic field da ya fi karfi. Lenz’s law of electromagnetic induction yana cewa hali na zarafin canza wannan zarafi zai canzawa musamman don bayar opposes magnetic field da ya faru shi. Hali na fadada wannan zarafi zai iya tabbatar da ita don Fleming’s right-hand rule.

Faraday’s law of induction yana nuna hali na tsari na transformers, motors, generators, and inductors. Kano tana da sunan Michael Faraday, wanda ya yi aiki a kan magnet da coil. A cikin aiki na Faraday, ya samu wani abu game da yadda EMF yana canzawa a cikin coil idan flux da ya gama da coil yana karfi.

Faraday’s Experiment

A cikin wannan aiki, Faraday ya ci abin da suka da magnet da coil da ya sa galvanometer across the coil. A cikin farkon aiki, magnet an rike, saboda haka ba da deflection a cikin galvanometer, ya'ni aiki na galvanometer an za a center ko zero position. Idan magnet an koma zuwa coil, aiki na galvanometer an koma zuwa wata hali.

Idan magnet an rike a wata hali, aiki na galvanometer an zo ne zuwa zero position. Idan magnet an koma daga coil, aiki na galvanometer an koma zuwa hali na biyu amma a nan aiki na galvanometer an zo ne zuwa zero position. Duk da haka, idan magnet an rike da coil an koma zuwa magnet, galvanometer an kamar da deflection. An samu cewa mafi yawan karfin magnetic field, mafi yawan induced EMF ko voltage a cikin coil.

Kasuwanci: Daga wannan aiki, Faraday ya ci cewa lokacin da akwai relative motion bayan conductor da magnetic field, flux linkage da coil yana karfi da wannan karfin yana canzawa voltage a cikin coil.

Michael Faraday ya kirki biyu na laws wajen aiki na uku. Wannan laws suna da sunan Faraday’s laws of electromagnetic induction.

Faraday’s First Law

Duk da yawan karfin magnetic field da coil na wire, zai canzawa EMF a cikin coil. Wannan EMF induced tana da sunan induced EMF, idan conductor circuit an kasa, current zai kuma circulate through the circuit and this current is called induced current.
Method to change the magnetic field:

1. By moving a magnet towards or away from the coil

2. By moving the coil into or out of the magnetic field

3. By changing the area of a coil placed in the magnetic field

4. By rotating the coil relative to the magnet

Faraday’s Second Law

It states that the magnitude of emf induced in the coil is equal to the rate of change of flux that linkages with the coil. The flux linkage of the coil is the product of the number of turns in the coil and flux associated with the coil.
