First of all, we're pretty sure that you're referring to "variation", not "declaration".
Magnetic variation is the difference between the direction from you to the north pole (called "true north"), and the direction in which your magnetic compass points.
That difference changes with your position on earth, because the north pole and the
place your compass points to are two different places. If you were standing at the point that's exactly halfway between them, then your compass would point exactly away from the north pole. And if you're not between them, but you're standing on the extension of the line between them, then your compass it pointing at the north pole, because both points are in the same direction from you.
If you look at a navigational map, you will see lines of magnetic variation printed on the map. If you read your magnetic compass and apply the magnetic variation (printed on the map), you can calculate the direction of TRUE north.
What else can I help you with?
What is the angular difference between true North and magnetic North is called?
There is a general geographical difference, called magnetic declination. In addition, there may be differences that arise locally, as a result of nearby objects that attract a magnet, which is called magnetic deviation. Related links are given below.
How far is earths magnetic axis tilted from its geographic axis?
Earth's magnetic axis is tilted at an angle of approximately 11 degrees from its geographic axis. This means that the magnetic north pole is not exactly aligned with the geographic north pole. The tilt causes compass needles to point slightly off from true north in certain locations.
What is of the Angle of magnetic north?
That all depends on WHERE on the earth you are located. The angle between the direction to the north geographic pole and the north magnetic pole is different at different places. Go to "Google.com" and search for "magnetic declination". You'll get plenty to read, and ways to determine what the angle is at your location.
Does the moon have a stronger magnetic field than the earth?
No, the moon does not have a global magnetic field like Earth. Some localized magnetic fields have been detected on the moon's surface, but they are much weaker than Earth's magnetic field.
Why are constellations seen at different places and time?
Constellations appear to be in different places at different times due to the Earth's rotation on its axis. As the Earth rotates, the position of the observer relative to the stars changes, causing different constellations to become visible. This is why different constellations can be seen in the night sky at different times and in different locations on Earth.
Where is the Earths magnetic field at its strongest?
The Earth's magnetic field is strongest at the North and South magnetic poles, which are not the same as the geographic North and South poles. The magnetic field strength varies at different locations on the Earth's surface.
Where are the earth's magnetic poles?
Deep within the earth, along an axis which 'wobbles' around the earth's axis of rotation. This causes the locations called 'Magnetic North' and 'Magnetic South' to shift relative to the locations called 'True North' and 'True South'. The magnetic polarities of the locations 'Magnetic North' and 'Magnetic South' are south and north, respectively.
Why would the magnetic declination be different in different locations?
The big iron ball in the center of the Earthis is suspended in liquid rock and not perfectly centered, spinning but not orientated perfectly to the Earths poles. STherefore, the Earth tends to wobble around it and the magnitic poles are far from the geographic poles. As seen from any place, these poles are then relatively in different directions.
Is the earths dip the same everywhere in the world?
No, the Earth's magnetic dip angle varies at different locations on Earth. The magnetic dip, also known as inclination, is the angle between the magnetic field lines and the horizontal plane, and it changes as you move from the magnetic North or South poles towards the equator.
Imaginary band connects two points on earth's surface with zero magnetic variation?
It is not possible to have a band connecting two points on Earth's surface with zero magnetic variation. Magnetic variation occurs due to differences in Earth's magnetic field at different locations, making it impossible for two points to have identical magnetic properties.
Why will the dip not be the same everywhere in the world?
The dip of the Earth's magnetic field varies because the field is not perfectly uniform and is influenced by the local geology of each region. Changes in the magnetic properties of the Earth's crust, as well as the distribution of magnetic minerals, can cause variations in the magnetic field strength and direction, resulting in different dip angles at different locations around the world.
Why would magnetic declaration be different for different locations on Earth?
First of all, we're pretty sure that you're referring to "variation", not "declaration".Magnetic variation is the difference between the direction from you to the north pole (called "true north"), and the direction in which your magnetic compass points.That difference changes with your position on earth, because the north pole and theplace your compass points to are two different places.

If you read your magnetic compass and apply the magnetic variation (printed on the map), you can calculate the direction of TRUE north.
Is the magnetic pole near the Earths true North Pole a magnetic south pole or a magnetic north pole?
Earths geographic North Pole is also currently a magnetic north pole. This is however not always the case because over geological time scales the Earth's magnetic poles flip as a result of changes of flow in Earth's molten core which produces Earth's magnetic field.
How yo find the magnetic field of earth at a particular place?
Using a compass is the easiest way. The needle is going to point to the Magnetic North Pole. That means that the compass needle is ALIGNED with the Magnetic Field Lines of the Earth's magnetic field at your current position.
Where in the world does the magnetic declination equal zero?
Magnetic declination equals zero at the magnetic poles, where the Earth's magnetic field lines are vertical. This occurs near the North Magnetic Pole and the South Magnetic Pole, although the precise locations shift over time due to changes in the Earth's magnetic field. Additionally, there are locations called agonic lines, where the declination is zero, found along certain latitudes across the globe.
How can the magnetic orientation of rocks be used to trace the way a continent moved as it drifted?
The magnetic orientation of rocks can be used to track the movement of continents by recording the direction and intensity of Earth's magnetic field at the time the rocks formed. When rocks solidify, they lock in the orientation of Earth's magnetic field. By comparing the magnetic orientation of rocks from different locations, geologists can determine how the continents have drifted over time.
Phenomenon of the Earth's magnetic pole being in different locations in the past?
The Earth's magnetic poles have moved over time due to fluctuations in the planet's magnetic field. This phenomenon is known as geomagnetic reversal. It is a natural process that happens over geological time scales and is caused by changes in the Earth's outer core. These reversals have occurred numerous times in the Earth's history.
