Compass Magnetic North Declination

Inspiration Compass Magnetic North Declination, Find the magnetic declination in usa.

Compass magnetic north declination. Click on the map to find the magnetic declination at your location. Magnetic declination or magnetic variation refers to the disparity in the angle between true north vs magnetic north. The difference between magnetic north and true north is magnetic declination in the continental us declination can vary from nearly 20 degrees east in places on the west coast to nearly 20 degrees west in places on the east coast. The angle a compass needle makes between true north and magnetic north is called declination.

Results you will see your declination value at the top of this magnetic values list. This calculator may be used to calculate the magnetic declination for a specified location and date based on the international geomagnetic reference field model. Remember easterly declination values are represented as positive numbers and westerly declination values are represented as negative numbers. Magnetic north is the north given by the magnetized compass needle and points in the direction of north in the earths magnetic field lines and true north or geographic north which is the direction of the geographic north pole.

Depending on where you are on the earth the angle of declination will be different from some locations the geographic and magnetic poles are aligned so declination is minimal but from other spots the angle between the two poles is pretty big. Learn how to use the magnetic declination with a compass. Magnetic declination changes over time and with location. Declination is positive east of true north and negative when west.

Magnetic declination sometimes called magnetic variation is the angle between magnetic north and true north. As the magnetic field changes all the time so does declination at any given location. Magnetic declination or magnetic variation is the angle on the horizontal plane between magnetic north the direction the north end of a magnetized 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 polethis angle varies depending on position on the earths surface and. Now you may want to go to our next learning page so you can learn how to use your declination value.

The difference between the north geographic pole and the north magnetic pole is called magnetic declination or usually just declination. Other components of the magnetic field may be calculated using the magnetic field calculator.
