Is the source of magnetic field analogue to the source of electric current.

Explanation

To determine if the source of a magnetic field is analogous to the source of electric current, we need to analyze both concepts step by step.

### Step-by-Step Solution:

1. **Understanding Electric Current**:
- Electric current is defined as the flow of electric charge. In most cases, this charge is carried by electrons in a conductor.
- The movement of these charged particles is characterized by a property called drift velocity, which is the average velocity of charged particles due to an electric field.
