WebFeb 28, 2024 · Faraday’s First Law of Electromagnetic Induction states that when a conductor is placed in a varying magnetic field, an emf is induced. If the circuit of the conductor is closed, a current is induced, known as the induced current. Faraday’s Second Law of Electromagnetic Induction states that the Emf induced inside a coil is equivalent … WebFaraday’s second law of EMI. According to Faraday’s second law of EMI, the induced EMF is directly equal to the change rate of magnetic flux linkage within a coil. The law has also outlined that with different turns in the coil, the magnetic flux gets directly affected by the association of the coil.
