Question

at the magnetic poles of the Earth a compass needle will be
1 vertical
2. bent slightly
3. horizontal
4. inclined at 45° to the horizontal​

Answer 1

Answer:

3

Explanation:

If the Earth's magnetic field were a perfect dipole, the compass needle would float aimlessly. ... Earth's magnetic field lines would be vertical at the magnetic north pole if the magnetic north pole coincided exactly with the geomagnetic north pole. So a compass held horizontally there would have no preferred direction
