It isn't. Navigation by the stars is far more accurate than navigation with a compass, as magnetic north is different at different locations while north determined by the stars is the same at all locations.
A freely suspended magnet responds to the magnetic field of the planet Earth. The Earth's magnetic north pole is close to its geographic north pole, so a compass points (approximately) north.
an aircraft is accelerated while on an east or west heading.
It is magnetic north (not geographical north), which is the north on a magnetic compass.
No. A compass, being at its heart a magnet, is attuned to Earth's magnetic north, which is currently near Canada's Ellesmere Island, and moving in the direction of Russia at approximately 40 miles (65 km.) per year.For most purposes, the geographic and magnetic north poles are close enough to make little difference; but as you approach one or the other, you have to use a conversion chart to find your true location.
magnetic north
When you sail with a magnetized needle, it will point towards the magnetic north pole. This is because the needle aligns itself with the Earth's magnetic field, which is used for navigation purposes.
you can travel Magnetic or true courses ie magnetic north and true north. Magnetic north is by way of compass
Compasses use the magnetic field to navigate always pointing North.

north pole Magnetic North PCH answer = Magnetic North

Because a ship is made of metal, which can affect the accuracy of a standard magnetic compass. Also, a gyrocompass is is better able to point to the true north, which is more accurate to navigation than magnetic North, which is not actually true North. Link below:
correctly when on a north or south heading.
I don't think that they spin in oposite directions if that's what you mean. Magnetic north and true north are completely unrelated. True north is a geographical location that lies on earth's axis. Magnetic north is just what they call it. At somepoint they must have noticed that earth's magnetic poles seemed to line up with north and south so that's what they named magnetic poles since they could be used for navigation. The core's spinning does cause the magnetic poles to move though.
Yes , well mostly. It actually points to magnetic north, which isn't exactly at the North Pole. The Earth's magnetic field is offset from true geographic north and the North Magnetic Pole is currently located in northern Canada. To arrive at true north, a table of deviations can be consulted. But for most purposes, it is close enough to actual north.
