Angle of dip is maximum at the poles.  A compass needle points to the north because it is the N pole of the compass and is attracted by the S pole of the earth. This does not mean that there is actually a magnet as such inside the earth. Rather, an electric current in the earth generates a magnetic field. If we hold a compass when we are near the North Pole, the N needle of the compass will try to point straight to the ground.
