Faraday's first law is related to which of the following?

Answer & step-by-step solution
Correct answer: A. Electromagnetic induction
Quick explanation

A — Electromagnetic induction. Faraday's first law states that an EMF is induced in a circuit whenever the magnetic flux linked with it changes.

Detailed solution (in the paper’s original language)

સમજૂતી

Faraday નો પ્રથમ નિયમ કહે છે કે circuit સાથે link થતો magnetic flux બદલાય ત્યારે circuit માં EMF induce થાય છે.

અેથી આ નિયમ electromagnetic induction સાથે સીધો સંબંધિત છે.

મુખ્ય ખ્યાલ

Flux linkage માં ફેરફાર થાય → induced EMF ઉત્પન્ન થાય.

પરીક્ષા મુદ્દો

First law (EMF induce થાય છે) અને second law (magnitude/rate of change) અલગ રાખો.

ઝડપી ટ્રિક

Faraday → electromagnetic induction.

બીજા વિકલ્પો ખોટા કેમ છે

Capacitance, heating effect અને mechanical motion અલગ topics છે; Faraday first law નો વિષય નથી.

સામાન્ય ભૂલ

Faraday’s law ને Joule’s heating law સાથે ગૂંચવવું.
