  1. The Earth has a magnetic field and the pointer is magnetic.

  2. Of gravitational force of the Earth.

  3. The compass needle points to cold places.

  4. The Earth doesn't have any magnetic field.

The Earth has a substantial magnetic field. No matter where you stand on the Earth, you can hold a compass in your hand and it will always align itself along the Earth's magnetic field.
