A ‘free floating magnetic needle’ at North Pole is parallel to the ‘surface of earth’.
Explanation:
- A free floating needle always aligns itself to the ‘magnetic north pole’ of the earth. The North Pole faces the ‘North Pole’ of the earth and vice versa.
- This is when the magnet is made to rest free in ‘North South Direction’.
- Now as the needle is taken in the North Pole which is the geometric North Pole it lies parallel to the surface of the earth because that is the direction it makes with the magnetic pole of the earth.
