what is TRUE north?
and what is magnetic north?
-------------------------------------------------------
answers:
spot a say: True North, the North pole, is the Northern centre of rotation of the Earth. The other centre of rotation is the South Pole.
The North magnetic pole is where the magnetic flux lines are concentrated. The magnetic field is generated by the spinning liquid outer core in the magnetic field of the solid iron core.Since it is liquid it can move under other influences and this causes the magnetic poles to migrate.
Please note : the North magnetic pole is actually a magnetic south pole.This allows the north pole of compass needles to point at it. Magnetic poles are neither negative nor positive

CarolOklaNola say: True north is GEOGRAPHIC north where the latitude is +90 degrees. True north is a point on the globe where the polar ice cap and Arctic ocean is.
Magnetic north is where the magnetic field lints are defined as being pointing down into the Earth's core and the magnetic polarity is DEFINED as being positive.. Magnetic north is NOT one single point because the location of magnetic north SHIFTS on several different cycles. Including a a daily cycle.; Earth's outer loquid core is rotating at different rate than Earth cruse and mantle. The rotain outer liquid core creates and maintains an extric m agnetic dynamo that creates Earth's dipole magnetic field. , which is NOT very strong when compared to Jupiter's and Saturn's global magnetic fields.
True north is geographic north.

The difference is defined as being magnetic declination.
