Right-hand thumb rule:
- Right-hand thumb rule states that if a current-carrying conductor is imagined to be held in the right hand such that the thumb points in the direction of the current, then the curled fingers indicate the direction of the magnetic field.
- If the current flows in the upward direction the direction of the magnetic field is clockwise, then the direction facing will be the North Pole.
- If the current flows in the downward direction the direction of the magnetic field is anticlockwise, then the direction facing will be the South Pole.
EXPLANATION:
Given - The current is passing through the loop in clockwise.
- Since the current passes through the loop in the clockwise direction, therefore, the front face of the loop will be the south pole and the back face, i.e., the face touching the table will be north pole.
- According to the right-hand rule, the direction of the magnetic field inside the loop will be pointing downward.
- Outside the loop, the direction of the magnetic field will be upward.
