true north is the direction towards the Geographic north pole, the point on the globe exactly 90 degrees north of the equator, and thru which the earth's rotational axis meets the surface. Magnetic north is the direction towards the magnetic north pole which is predicted* to be located at 82.7 degrees north latitude, and 114.4 degrees west longitude (just north of Canada). Magnetic north is where a compass actually points to, so you must adjust your compass acordingly.
*this is predicted because magnetic drift causes the pole to move from year to year.
True. Declination is the angular difference between true north (the direction of the North Pole) and magnetic north (the direction a compass points towards).
True magnetic bearing is the angle measured clockwise from true north to a destination point. It takes into account the magnetic declination, which is the difference between true north and magnetic north at a specific location. This type of bearing is important for accurate navigation using a magnetic compass.
magnetic variation
A compass points towards magnetic north, which is the direction that a magnetic needle aligns itself with the Earth's magnetic field. This is not the same as true north, which is the geographic North Pole. The difference between magnetic north and true north is known as magnetic declination and varies by location.
To find the variation from true north, you can use a magnetic compass to determine the magnetic north and then calculate the angle between the magnetic north and the true north. This angle is known as the magnetic declination or variation. Many maps and GPS devices provide information about the current magnetic declination in a specific location.
you can travel Magnetic or true courses ie magnetic north and true north. Magnetic north is by way of compass

This is not the same as true north, which is the geographic North Pole. The difference between magnetic north and true north is known as magnetic declination and varies by location.
It is measured exactly the same in the Southern hemisphere (no difference between the two hemispheres). It is the difference between magnetic north and true north and it varies all over the globe. Magnetic declination (also called magnetic variation) is positive when magnetic north is east of true north (clockwise) and it is negative when magnetic north is west of true north (anti-clockwise).
'Magnetic North' is the name given to a location in the Arctic, to differentiate it from 'True North'. Whereas True North is fixed and located at the Earth's axis of rotation, the 'Magnetic North' varies from year to year. The term, 'Magnetic North', does not describe the magnetic polarity at that location which, actually, is a south pole.
To find the variation from true north, you can use a magnetic compass to determine the magnetic north and then calculate the angle between the magnetic north and the true north. This angle is known as the magnetic declination or variation. Many maps and GPS devices provide information about the current magnetic declination in a specific location.
True north relates to what we consider the north pole. However the axis on magnetic terms isn't in the same location. Magnetic north is still north but there is an angle difference between the two.
