Q29: Which of the following statements is not correct for electromagnetic... - Electromagnetic Induction and Alternating Currents - Physics CUET UG 13-05-2025 Shift 2 Paper | Agrigyan

According to Faraday's law of electromagnetic induction:

• The induced emf is equal to the time rate of change of magnetic flux ($d\Phi_B/dt$), not the total flux change ($\Delta\Phi_B$). Hence, statement 2 is incorrect.
• Statement 1 accurately states Faraday's law magnitude.
• Statement 3 is correct because $\mathcal{E} \propto N$.
• Statement 4 is a direct statement of Lenz's law.
