What is the direction of the magnetic field around a current-carrying wire?
  1. Radially inward
  2. Radially outward
  3. Clockwise or counterclockwise depending on current direction
  4. Perpendicular to the wire

Questions & Step-by-Step Solutions

What is the direction of the magnetic field around a current-carrying wire?
  • Step 1: Identify the direction of the electric current flowing through the wire.
  • 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 shows the direction of the magnetic field lines.
  • Step 4: If the current flows upwards, the magnetic field will circle the wire in a counterclockwise direction when viewed from above.
  • Step 5: If the current flows downwards, the magnetic field will circle the wire in a clockwise direction when viewed from above.
