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 north is the geographical location at the North Pole, while magnetic north is the direction to which a compass needle points due to Earth's magnetic field. The difference between true north and magnetic north is called magnetic declination, and it can vary depending on your location on Earth.
The geographic north pole is related to Earth's rotation. The magnetic north pole is related to the Earth's magnetic field. The magnetic north pole is near the geographic southpole, but not exactly so.

No. The magnetic north pole is the place on the Earth's surface where the magnetic feild lines point directly downwards (It is where the compass points). The geographic north pole is the place where the Earth's axis touches the surface (It is what the Earth turns around).
Geographic north - often just called north - has to do with Earth's axis of rotation. Magnetic north has to do with Earth's magnetic field, and it is not exactly aligned with the geographic axis. The magnetic north pole is a few thousand kilometers off the geographic south pole (or north pole, depending on the definition used).
In HSC studies, and any study for that fact, only use MAGNETIC north as it remains constant and actually allows the latitude and longitude system of positioning to function. True north is marked by stars and hence is not always exactly the same where as magnetic north will always show the same results.
At Bay St. Lawrence, on the northern tip:
Mag is 19°22' west of True
Decreasing 10' per year.
At Halifax:
Mag is 18°8' west of True.
Decreasing 8' per year.
At Barrington, on the southern tip:
Mag is 17°21' west of True
Decreasing 6' per year.
No. The physical "north pole", at the axis of the Earth's rotation, does not move. The magnetic pole DOES move, and has been moving from northern Canada across the Arctic Ocean. In another 100 years or so, it will be in Russia.
Magnetic compasses point toward the magnetic pole. Most maps are overprinted with lines of "magnetic variation", the difference between magnetic north and true north.

What is true magnetic bearing?
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.
True or false Declination is the difference between true north and magnetic north?
True. Declination is the angular difference between true north (the direction of the North Pole) and magnetic north (the direction a compass points towards).
What is the name given to the difference between true north and magnetic north?
magnetic variation
A way to find the variation from true north?
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.
What is the name of the difference of true north and magnetic north?
The difference is referred to as magnetic, or compass, declination.
What do you mean by true course in navigation?
you can travel Magnetic or true courses ie magnetic north and true north. Magnetic north is by way of compass
Is wind direction from true north or magnetic north?
True North...
Does gps indicate true north or magnetic north?
True North
What is the Is the difference between true North and magnetic north?
magnetic variation
True or false Declination is the difference between true north and magnetic north?
True. Declination is the angular difference between true north (the direction of the North Pole) and magnetic north (the direction a compass points towards).

How is magnetic declination measured in the northern hemisphere?
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).
What is magnetic variation?
Magnetic variation is the angle between true north (the direction pointing to the North Pole) and magnetic north (the direction a compass needle points). It varies depending on location and changes over time due to shifts in the Earth's magnetic field. Pilots and navigators use magnetic variation to accurately navigate using a compass.
Why are there 2 norths magnetic north and the true north?
Magnetic north is the direction towards which a compass needle points, influenced by the Earth's magnetic field. True north, on the other hand, refers to the geographic North Pole, the point at which the Earth's rotational axis intersects its surface. The discrepancy between magnetic north and true north is known as magnetic declination and varies depending on the location on Earth.

What does magnetic north mean?
'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.
