The magnetic lines of force created by current carrying conductor shall be in clockwise direction when viewed from East side. Refer sketch enclosed for details.
Explanation:
As per Right Hand Rule to find direction of magnetic lines of force, if the right hand is placed with four fingers curled and the thumb kept straight such as to indicate the conventional direction of current. Conventional current is defined as the current that flows in the direction opposite to the direction of the flow of electrons in the electrical circuit.
