What is the shape of the magnetic field lines around a long straight conductor carrying current?
Step 1: Imagine a long straight wire that is carrying an electric current.
Step 2: Understand that when current flows through the wire, it creates a magnetic field around it.
Step 3: Visualize the wire as the center point of a circle.
Step 4: The magnetic field lines form circles around the wire, like rings around a tree trunk.
Step 5: These circles are called concentric circles because they share the same center (the wire).
Step 6: The direction of the magnetic field lines 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.
