Difference between magnetic meridian and geographical meridian?

A magnetic meridian is a line passing through a location connecting its magnetic north and south poles, while a geographical meridian is a line passing through a location connecting its geographic north and south poles. The magnetic meridian is affected by the Earth's magnetic field, while the geographical meridian is based on the Earth's rotation.


Why does the earth rotate along its magnetic meridian?

It doesn't. The north pole and the north magnetic pole are miles apart.


Why do we need to orient entire set up in magnetic meridian before performing experiment?

Orienting the setup in the magnetic meridian helps ensure accuracy in experiments involving magnetic fields because it aligns the equipment with the Earth's magnetic field. This alignment reduces interference from external magnetic fields and produces more reliable results.


What is magnetic meridian in compass surveying?

The magnetic meridian in compass surveying is the line passing through a compass needle when it is freely suspended and allowed to align with the Earth's magnetic field. It represents the direction of the magnetic north pole at a particular location on the Earth's surface. It is an important reference in compass surveying for determining directions.


What is inclined at an angle of 11.5 degrees to earth's rotational axis?

magnetic meridian


A dip needle in a plane perpendicular to magnetic meridian will remain?

horizontal with its north pole pointing towards magnetic north.


What is the difference between magnetic meridian and geographical meridian?

the vertical plane passing through magnetic axis is magnetic meridain and the vertical plane passing through geographical axis in geographical meridain.the intersting fact is they are not parallel...but remain at certain angle ..the maximum angle made is 17 degree


What cause deviation in a magnetic compass?

The compass needle will only align itself with the magnetic meridian if it is free from all other influences except the magnetic field of earth.This is rarely so, particularly on a ship which constructed on steel. The magnetism induced in the steel by the earths magnetic field causes the compass needle to deviate from the magnetic meridian, by an amount which is called the DEVIATION.


What is the name of the line with whcih a compass aligns?

The line with which a compass aligns is called the magnetic meridian. This line indicates the direction of the Earth's magnetic field at a specific location. Compasses point towards magnetic north, which is generally close to, but not the same as, true north, due to the Earth's magnetic field being irregular.


What exactly is a tied gyro and how do they 'tie' it?

It is a horizontal gyroscope employing a 2 degree-of-freedom gyroscope with its spin axis aligned with the earth's magnetic meridian


How many norths are there?

There are three norths: true north, magnetic north and grid north. According to www.ordnancesurvey.co.uk, the three norths are defined as follows: Grid North: the direction of a grid line which is parallel to the central meridian on the National Grid. True North: the direction of a meridian of longitude which converges on the North Pole. Magnetic North: the direction indicated by a magnetic compass. Magnetic North moves slowly with a variable rate and currently is west of Grid North in Great Britain.


Is Every meridian is distorted by magnetic declination?

No. The meridians are where they are because their location is defined. Magnetic effects don't distort them, any more than you could use a magnet to move the 47/8-inch mark to a different place on a ruler.
