Solution
The correct answers are:
- The Earth's magnetic field may reverse polarity from North to South in the future.
- The Earth's magnetic field is generated dynamically by electrically conducting, convecting molten metals and a moderately rapid rotation.
The Earth's magnetic north pole does not remain at a stationary location with time, it actually moves. The magnetic field is not generated by a stable bar-like magnet at the Earth's core. Also, the magnetic north pole is not constantly aligned with Earth’s geographic north pole.
