North Magnetic Pole
At any other place on earth, the magnetic field points to the North Magnetic Pole. This is why a compass works to find where north is.
The North Magnetic Pole is not identical to the North Pole, which is the geographic north pole. It wanders slowly. In 2001, a team of scientists estimated that the North Magnetic Pole is near Ellesmere Island in northern Canada at . It was estimated to be at in 2005. As of 2015, the pole is thought to have moved east beyond the Canadian Arctic territorial claim to .
Because the North Magnetic Pole is different from the North Pole, a compass does not always point straight north. But usually the difference is small.
