An electric current predominantly produces _field around it.

Options

A. magnetic
B. electric
C. gravitational
D. all the above

Answer

To answer the question "An electric current predominantly produces _field around it," we need to identify the type of field that is primarily associated with electric current.

### Step-by-Step Solution:

1. **Understanding Electric Current**: Electric current is the flow of electric charge, typically through a conductor like a wire.

2. **Identifying the Fields Associated with Electric Current**: Electric current can produce different types of fields:
- **Electric Field**: This is produced by static charges and is present around charged objects.
- **Magnetic Field**: This is produced when electric charges are in motion (i.e., when there is an electric current).

3. **Focusing on the Motion of Charges**: Since electric current involves the movement of charges, we focus on the magnetic field. According to electromagnetic theory, a moving charge creates a magnetic field around it.

4. **Conclusion**: Therefore, the predominant field produced by an electric current is the **magnetic field**.

5. **Final Answer**: An electric current predominantly produces a **magnetic field** around it.
