What is the direction of the magnetic field due to a current flowing in a circular loop when viewed from above? (2023)

Step 1: Imagine you are looking down at a circular loop of wire from above.
Step 2: Determine the direction of the current flowing in the loop. For this example, let's say the current flows in a counterclockwise direction.
Step 3: Use your right hand to apply the right-hand rule. Point your thumb in the direction of the current flow (counterclockwise).
Step 4: Curl your fingers around the loop. Your fingers will wrap in the direction of the current.
Step 5: Notice that your thumb points upwards, which indicates the direction of the magnetic field.
Step 6: Conclude that if the current flows counterclockwise when viewed from above, the magnetic field direction is out of the plane (towards you).
