What is the direction of the magnetic field produced by a current-carrying wire according to the Biot-Savart Law?

Correct Answer: Perpendicular to the wire and current direction

Step 1: Identify the current-carrying wire. This is the wire through which electric current is flowing.
Step 2: Determine the direction of the current in the wire. This is the direction in which positive charge would flow.
Step 3: Use the right-hand rule to find the direction of the magnetic field. Point your thumb in the direction of the current.
Step 4: Curl your fingers around the wire. The direction your fingers curl represents the direction of the magnetic field lines.
Step 5: Understand that the magnetic field is perpendicular to both the wire and the direction of the current.
