Who and when discovered the earth’s magnetic poles?

The magnetic pole is a conditional point on the earth’s surface, in which the earth’s magnetic field is directed strictly at an angle of 90 degrees upward. There are two magnetic poles on Earth: North and South. The first was discovered by the North Magnetic Pole in 1831 by the English polar explorer John Ross in the Canadian archipelago. The South Magnetic Pole was discovered only in 1909 by Ernest Henry Shackleton’s British Antarctic Expedition.
