He is known mainly for his work on the temperature of the earth and his construction of a compass to measure magnetic dip at sea.
12.
The greatest currents and voltages were obtained when the difference in depth was such that a line joining the two electrodes was in the direction of the magnetic dip, or magnetic inclination.
13.
Because of magnetic dip the compass will show a false turn towards the north if in the northern hemisphere or vice versa a false turn towards the south if in the southern hemisphere.
14.
The characteristic signature of the EEJ is a sharp negative V-shaped curve in the \ Delta H field, attaining its minimum within 0.5?of the magnetic dip equator.
15.
The Earth's North and South Magnetic Poles are also known as "'Magnetic Dip Poles "', with reference to the vertical " dip " of the magnetic field lines at those points.
16.
Magnetic declination should not be confused with "'magnetic inclination "', also known as magnetic dip, which is the angle that the Earth's magnetic field lines make with the downward side of the horizontal plane.
17.
The back of the 200 kroner note shows a map of the north polar regions including Scandinavia to the right and northern Canada to the left . A ring encircling the magnetic dip pole ( located near Resolute, Canada ) symbolizes the location of auroral phenomena including the satellite-determined statistical location of Birkeland currents.
