Questions & Step-by-Step Solutions

What is the direction of the magnetic field around a straight conductor carrying current? (2023)
  • Step 1: Identify the straight conductor that is carrying an electric current.
  • Step 2: Determine the direction of the current flow in the conductor (from positive to negative).
  • Step 3: Use the right-hand rule: Point your thumb in the direction of the current flow.
  • Step 4: Curl your fingers around the conductor. The direction your fingers curl indicates the direction of the magnetic field.
  • Step 5: When viewed from the positive end of the conductor, the magnetic field will appear to move in a counterclockwise direction.
