What is the magnetic field around a straight current-carrying conductor? (2023)
Step 1: Understand that a current-carrying conductor is a wire through which electric current flows.
Step 2: Recognize that when electric current flows through the wire, it creates a magnetic field around it.
Step 3: Visualize the magnetic field as circles that are centered around the wire.
Step 4: Know that these circles are called concentric circles because they share the same center (the wire).
Step 5: Remember that the direction of the magnetic field can be determined using the right-hand rule: if you point your thumb in the direction of the current, your fingers curl in the direction of the magnetic field lines.
