Options

A. Amperes law
B. Coulomb law
C. Lenz’s law
D. Faraday’s law

Answer

To solve the question regarding the induced electromotive force (e.m.f.) produced by a moving conductor coil in a magnetic field, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept**:
- A conductor coil moving through a magnetic field experiences a change in magnetic flux. According to electromagnetic induction principles, this change induces an electromotive force (e.m.f.).

2. **Identify the Law**:
- The phenomenon of induced e.m.f. due to a change in magnetic flux is described by Faraday's Law of Electromagnetic Induction.

3. **State Faraday's Law**:
- Faraday's Law states that the induced e.m.f. (E) in a closed loop is equal to the negative rate of change of magnetic flux (Φ) through the loop:
\[ E = -\frac{d\Phi}{dt} \]
- Here, \(d\Phi\) represents the change in magnetic flux, and \(dt\) represents the change in time.

4. **Application to the Problem**:
- In the case of a moving conductor coil, as it moves through the magnetic field, the magnetic flux linked with the coil changes, leading to the induction of e.m.f. This is a direct application of Faraday's Law.

5. **Conclusion**:
- Therefore, the statement "A moving conductor coil in a magnetic field produces an induced e.m.f." is in accordance with Faraday's Law.

6. **Final Answer**:
- The correct answer is **Faraday's Law**.
