A current carrying wire produces in the neighbourhood

Options

A. (a)Electric and magnetic fields
B. (b)Electric field only
C. (c)Magnetic field only
D. (d)No field

Answer

To solve the question "A current carrying wire produces in the neighbourhood," we need to analyze the effects of a current-carrying wire on its surroundings.

### Step-by-Step Solution:

1. **Understanding the Concept**: A current-carrying wire generates a magnetic field around it. This is a fundamental principle in electromagnetism.

2. **Identify the Type of Current**: The question does not specify whether the current is steady (constant) or varying (changing over time). However, for the purpose of this question, we will assume it is a steady current.

3. **Magnetic Field Production**: According to Ampère's circuital law, a steady current produces a magnetic field in the surrounding space. The direction of this magnetic field can be determined using the right-hand rule.

4. **Electric Field Production**: A steady current in a wire does not produce an electric field in the surrounding space. An electric field is produced only when there is a change in electric charge distribution or when the current is varying.

5. **Conclusion**: Since we are considering a steady current, the current-carrying wire produces only a magnetic field in its neighborhood. Therefore, the correct answer is that it produces a magnetic field only.

### Final Answer:
A current-carrying wire produces a magnetic field only in the neighborhood.
