Faraday law represents :

Options

A. relation between I and B
B. relation between magnetic force and magnetic field
C. relation between e/m/f and rate of change of flux
D. none of these

Answer

### Step-by-Step Solution:

1. **Understanding Faraday's Law**: Faraday's law of electromagnetic induction states that the induced electromotive force (EMF) in any closed circuit is equal to the rate of change of magnetic flux through the circuit.

2. **Mathematical Representation**: The law can be mathematically expressed as:
\[ E = -\frac{d\Phi}{dt} \]
where:
- \(E\) is the induced EMF,
- \(\Phi\) is the magnetic flux,
- \(\frac{d\Phi}{dt}\) is the rate of change of magnetic flux.

3. **Identifying the Components**:
- The negative sign indicates that the induced EMF generates a current that opposes the change in magnetic flux (Lenz's Law).
- The term \(\frac{d\Phi}{dt}\) represents how quickly the magnetic flux is changing over time.

4. **Analyzing the Options**:
- The question asks which statement correctly represents Faraday's law.
- The correct relationship is between the induced EMF and the rate of change of magnetic flux.

5. **Conclusion**: Therefore, the correct option is the one that states the relationship between induced EMF and the rate of change of magnetic flux.

### Final Answer:
The correct representation of Faraday's law is the relationship between induced EMF and the rate of change of magnetic flux.
