MCQ
A compass needle, which shows the direction at the earth's magnetic pole is:
- ✓Vertical.
- BNo particular direction.
- CBent at $45^\circ $ to the vertical.
- DHorizontal.
✓
Answer
Correct option: A.
Vertical.
For a compass to show the direction of magnetic pole moment, they must be placed at ether of the $2$ geographic poles. It is because the direction of magnetic moment is from south to north pole.
The compass therefore will be vertical at both the poles.
