Question
Current is flowing through a conductor and creates a magnetic field. Assume that this is the only source of the magnetic field. Reversing a current in a straight conductor with no change to the magnitude(ampere value) will cause a _________.

Solution
The correct option is C Reversal of the direction of the magnetic field
The direction of the magnetic field due to a current carrying wire can be determined using Right hand thumb rule. Using your right-hand, point your thumb in the direction of the current. Now, curl your fingers into a half-circle around the wire, they point in the direction of the magnetic field. So, Reversing a current in a straight conductor with no change to the magnitude(ampere value) will cause a reversal of the direction of the magnetic field.
