<P> Magnetic declination , or magnetic variation , is the angle on the horizontal plane between magnetic north ( the direction the north end of a compass needle points , corresponding to the direction of the Earth 's magnetic field lines ) and true north ( the direction along a meridian towards the geographic North Pole ) . This angle varies depending on position on the Earth 's surface and changes over time . </P>
