What is the direction of the magnetic field produced by a current-carrying wire when viewed from one end? (2023)

Step 1: Identify the direction of the electric current flowing through the wire. This can be from positive to negative.
Step 2: Use your right hand to apply the right-hand rule. Point your thumb in the direction of the current.
Step 3: Curl your fingers around the wire. The direction your fingers curl represents the direction of the magnetic field lines.
Step 4: If you are looking at one end of the wire, the direction of the magnetic field will be in the direction your fingers point.
