Understanding the Right-Hand Rule
The most common way to visualize this is using the right-hand rule:
1. Point your thumb in the direction of the current flow. Since the current is flowing towards you, point your thumb directly at your face.
2. Curl your fingers around the conductor. Your curled fingers now represent the direction of the magnetic field lines.
The Result
If the current is flowing towards you, the magnetic field lines will form circles around the conductor in a counter-clockwise direction when viewed from above.
Key Points
* Direction is crucial: The direction of the current dictates the direction of the magnetic field. Reverse the current, and the field lines will also reverse direction.
* Strength varies: The strength of the magnetic field decreases as you move further away from the conductor.
