The correct Answer is:
To solve the assertion and reason question, we will analyze both statements and determine their validity and relationship. ### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that the total induced EMF in a loop is not confined to any particular point but is distributed around the loop in direct proportion to the resistances of its parts. - This means that when an EMF is induced in a circuit, it does not act at a single point but rather affects the entire loop. The distribution of this EMF depends on the resistance of each segment of the loop. 2. **Understanding the Reason (R)**: - The reason states that in general, when there is no change in magnetic flux, no induced EMF is produced. - This is based on Faraday's law of electromagnetic induction, which states that an EMF is induced in a circuit when there is a change in magnetic flux through the circuit. 3. **Analyzing the Relationship**: - The assertion is true because the induced EMF indeed affects the entire loop and is distributed according to the resistances. - The reason is also true because it accurately describes the condition under which EMF is induced (i.e., a change in magnetic flux). - However, the reason does not explain the assertion. The assertion discusses the distribution of EMF, while the reason discusses the condition for its existence. 4. **Conclusion**: - Both the assertion and reason are true, but the reason does not explain the assertion. Therefore, the correct answer is that both statements are true, but the reason does not explain the assertion. ### Final Answer: - Both A and R are true, but R does not explain A. ---

A metallic loop is placed in a nonuniform magnetic field. Will an emf be induced in the loop?

A closed loop with the geometry shown in Fig. 3.9 is placed in a uniform magnetic field direction into the plane of the paper. If the magnetic field decreases with time, determine the direction of the induced emf in this loop.

Assertion If a loop is placed in a non-uniform (with respect to position) magnetic field, then induced emf is produced in the loop. Reason In a non-uniform magnetic field, magnetic flux passing through the loop will change. Therefore, induced emf is produced.
