the angle on the horizontal plane between magnetic north (, the direction in which the north end of a compass needle points

Magnetic declination or variation is the angle on the horizontal plane between magnetic north (the direction the north end of a compass needle points, corresponding to the direction of the Earth's magnetic field lines) and true north (the direction along a meridian towards the geographic North Pole).

the angle on the horizontal plane between magnetic north (, the direction the north end of a compass needle points

Magnetic declination is the angle on the horizontal plane between magnetic north (the direction the north end of a compass needle points, corresponding to the direction of the Earths magnetic field lines and True North (the direction along a meridian towards the geographic North Pole).

The angle between true north and magnetic north

Angle between true north and magnetic north is called magnetic declination and most of the maps have marked a measured local magnetic declination to allow the map to be oriented with a compass parallel to true north.

This difference between Magnet North and the True North

This difference between Magnet North and the True North is called Magnetic Declination.

The angle between the magnetic direction and the true polar direction

The angle between the magnetic direction and the true polar direction is called the magnetic declination.

the difference between magnetic north (or south) pole

Magnetic declination (variation) is the difference between magnetic north (or south) pole as indicated by a magnetic compass, and the true geographic north (or south) pole around which the earth rotates.

The horizontal angle between the magnetic meridian and the true meridian

The horizontal angle between the magnetic meridian and the true meridian is known as magnetic declination.

The difference between the true direction and magnetic direction

The difference between the true direction and magnetic direction is called magnetic declination.

The angle between magnetic meridian at a point and

The angle between magnetic meridian at a point and geographical meridian is called the magnetic declination.
