Answer the following questions:
What is the relationship between an electric current and a magnetic field?

Explanation

### Step-by-Step Solution:

1. **Understanding Electric Current**: Electric current is the flow of electric charge, typically carried by electrons in a conductor. It is measured in amperes (A).

2. **Understanding Magnetic Field**: A magnetic field is a region around a magnetic material or a moving electric charge within which the force of magnetism acts. It is represented by magnetic field lines, which indicate the direction and strength of the magnetic field.

3. **First Relationship - Current Produces Magnetic Field**: When an electric current flows through a conductor (like a wire), it generates a magnetic field around it. This can be demonstrated by placing iron filings around a current-carrying wire; the filings will align themselves along the circular magnetic field lines created by the current.
