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

To solve the question regarding what Faraday's law represents, we can follow these steps:

### Step-by-Step Solution:

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

2. **Identify the Options**:
The options provided are:
- A) Relation between current (I) and magnetic field (B)
- B) Relation between magnetic force and magnetic field
- C) Relation between EMF and the rate of change of magnetic flux
- D) None of these

3. **Analyze Each Option**:
- **Option A**: This option talks about the relationship between current and magnetic field, which is not what Faraday's law describes.
- **Option B**: This option refers to the relationship between magnetic force and magnetic field, which is also not the focus of Faraday's law.
- **Option C**: This option correctly describes Faraday's law, which states that the induced EMF is proportional to the rate of change of magnetic flux.
- **Option D**: This option states that none of the above are correct, which is false since option C is correct.

4. **Select the Correct Answer**:
Based on the analysis, the correct answer is **Option C**: the relation between EMF and the rate change of magnetic flux.

### Final Answer:
**Faraday's law represents the relation between EMF and the rate change of magnetic flux (Option C).**
