What is the direction of the magnetic field around a current-carrying conductor? (2019)

Step 1: Understand that a current-carrying conductor is a wire through which electric current flows.
Step 2: Identify the direction of the electric current. The current flows from the positive side to the negative side.
Step 3: Use your right hand to apply the right-hand rule. Point your thumb in the direction of the current (positive to negative).
Step 4: Curl your fingers around the wire. The direction your fingers curl shows the direction of the magnetic field lines around the conductor.
Step 5: Note that when viewed from the positive current side, the magnetic field direction is counterclockwise.
