What happens to the direction of the magnetic field about an electric current when the direction of the current is reversed?

Respuesta :

Answer:

The direction of the magnetic field is also reversed.

Explanation:

  • The direction of the magnetic field is also reversed when viewed form the same side if the direction of current is reversed. The direction of the magnetic field with respect to the direction of electric current is determined by the Maxwell's right-hand thumb rule.
  • According to this rule we place our palm with the thumb pointing the direction of current flow and curling our finger in an action of gripping the wire. This position the the direction of curled fingers represents the direction of magnetic field.
