The displacement current was named as current because

Options

A. it is similar to conduction curren
B. it produces magnetic field
C. it is a time varying electrical field
D. it is current due to uniformly moving charges

Answer

To answer the question "The displacement current was named as current because," we can analyze the options provided and derive the correct reasoning step by step.

### Step-by-Step Solution:

1. **Understanding Displacement Current**:
Displacement current is a concept introduced by James Clerk Maxwell to address the situation in which a changing electric field can produce effects similar to those of a conventional current, even in the absence of actual charge carriers.

2. **Identifying the Options**:
- **Option A**: It is similar to conduction current.
- **Option B**: It produces magnetic field.
- **Option C**: It is a time-varying electric field.
- **Option D**: It is current due to uniformly moving charges.

3. **Analyzing Each Option**:
- **Option A**: While displacement current has similarities to conduction current, it is not entirely accurate to say it is similar, as they arise from different phenomena.
- **Option B**: Displacement current does produce a magnetic field, which is a key reason for its naming. This magnetic field arises from the changing electric field in the region between the plates.
- **Option C**: While the electric field is indeed time-varying, this option does not directly explain why it is called "current."
- **Option D**: Displacement current is not due to uniformly moving charges; this description fits conventional current better.

4. **Conclusion**:
The most accurate reason for why displacement current is called "current" is that it produces a magnetic field, similar to how conduction current does. Therefore, the correct answer is **Option B: It produces magnetic field**.

### Final Answer:
The displacement current was named as current because it produces a magnetic field.
