Changing magnetic fields can set up current loops in nearby metal bodies and the currents are called as

Options

A. eddy currents
B. flux currents
C. alternating currents
D. leaking currents

Explanation

To solve the question, we need to identify what type of currents are induced in nearby metal bodies due to changing magnetic fields. Let's break it down step by step:

### Step-by-Step Solution:

1. **Understanding the Concept**:
- When there is a changing magnetic field in a region, it can induce currents in nearby conductive materials. This phenomenon is described by Faraday's law of electromagnetic induction.

2. **Identifying the Type of Current**:
- The currents induced in these conductive materials due to the changing magnetic field are not the same as the conventional currents that flow in a circuit. Instead, they form closed loops within the material.

3. **Defining Eddy Currents**:
- The currents that are induced in this manner are specifically referred to as "eddy currents." These currents flow in circular paths or loops within the conductor, hence the name "eddy."

4. **Evaluating the Options**:
- Now, let's look at the options provided:
- Option 1: Eddy current
- Option 2: Flux current
- Option 3: Alternating currents
- Option 4: Leaking current
- Among these options, "eddy current" is the term that correctly describes the currents induced in nearby metal bodies due to changing magnetic fields.

5. **Conclusion**:
- Therefore, the correct answer to the question is **Option 1: Eddy currents**.
