Comment on "Survey Tracks Current Position of South Magnetic Pole " and "Recent Acceleration of the North Magnetic Pole Linked to Magnetic Jerks"
In recent months,two articles have appeared in Eos reporting new positions of the north [Newitt et al., 2002] and south [Barton, 2002] magnetic poles from on-site measurements of locations for vertical magnetic field dip.Readers should be advised that these reported positions are neither magnetic po...

| Summary: | In recent months,two articles have appeared in Eos reporting new positions of the north [Newitt et al., 2002] and south [Barton, 2002] magnetic poles from on-site measurements of locations for vertical magnetic field dip.Readers should be advised that these reported positions are neither magnetic poles nor geophysically important locations. First let us review some facts about our Earth's field. When a magnetic field can be represented by an axially symmetric dipole pattern similar to the electric field from a pair of equal and opposite electric charges, the axis of this magnetic field is called a pole.For the Earth,Gilbert [1958] first called attention to this dipole feature |
