The correct Answer is:
To solve the assertion and reason question, we will analyze both statements step by step. ### Step 1: Understand the Assertion The assertion states: "When a conducting loop is kept stationary in a non-uniform magnetic field, an emf is induced." - A conducting loop in a magnetic field experiences an induced electromotive force (emf) when there is a change in magnetic flux through the loop. - A non-uniform magnetic field means that the strength of the magnetic field varies from one point to another. - However, if the loop is stationary and there is no change in the magnetic field strength at the location of the loop, there will be no change in magnetic flux through the loop. **Conclusion:** The assertion is false because a stationary loop in a non-uniform magnetic field does not necessarily induce an emf unless there is a change in magnetic flux. ### Step 2: Understand the Reason The reason states: "As per Faraday's law, whenever flux changes, an emf is induced." - Faraday's law of electromagnetic induction states that the induced emf in a closed loop is directly proportional to the rate of change of magnetic flux through the loop. - This means that if there is any change in the magnetic flux (either due to a change in the magnetic field strength, the area of the loop, or the angle between the magnetic field and the normal to the loop), an emf will be induced. **Conclusion:** The reason is true as it accurately describes Faraday's law. ### Final Conclusion - The assertion is false, and the reason is true. Therefore, the correct answer is that the assertion is false while the reason is true.
