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
Why does a magnetic needle come to rest in north south direction?
A magnetic needle comes to rest in the north-south direction due to the Earth's magnetic field, which generates a magnetic force that aligns the needle. The Earth acts like a giant magnet with a magnetic north and south pole, causing the needle's magnetic ends to orient themselves along these lines. When the needle is free to rotate, it experiences torque from the Earth's magnetic field until it stabilizes in alignment with the magnetic field lines. This alignment minimizes the potential energy of the system, leading to the stable north-south orientation.
How is magnetic evidence preserved in the rocks that form along an ocean ridge?
Iron minerals that are present in magma or lava along the ridge that has not completely crystallized into rock are aligned with the Earth's polarity. When the magma or lava cools and solidifies completely, the magnetic orientation of the Earth at that time is preserved in the body of igneous rock.
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 an ordinary bar magnet doesn't rotate and align itself with party's magn3tic field when you place it on a table?
An ordinary bar magnet does not rotate and align itself with the Earth's magnetic field when placed on a table because it is not freely suspended. For a magnet to align with a magnetic field, it needs to be able to rotate freely, allowing its magnetic poles to respond to the external field. When placed on a stable surface like a table, friction and support prevent it from moving, thus inhibiting the alignment with the magnetic field.
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.
What is magnetic meridian?
The magnetic meridian is an imaginary line that represents the direction of the Earth's magnetic field at a particular location on the Earth's surface. It is defined as the vertical plane passing through a magnetic needle or compass that is free to align itself with the Earth's magnetic field.
What is inclined at an angle of 11.5 degrees to earth's rotational axis?
magnetic meridian
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 the difference between magnetic meridian and geographical meridian?

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 the circumference of the Earth along the Prime Meridian?
The Prime Meridian only extends from the North Pole to the South Pole along the 0° longitude line,which is only half of the Earth's circumference.The circumference of the Earth that includes the Prime Meridian is a polar circumference measuring approximately 40,008 km (about 24,860 miles), which is shorter than the equatorial circumference by about 67 km (42 miles), not including elevation above or below MSL.
What creates the Earths magnetic field?
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
When the earth is divided along the prime meridian you are in the?
East if you are one side of it and the west when you are on the other side of it.
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 does a compass determine direction?
A compass is a free-spinning magnet that will align itself to be parallel to the Earth's magnetic field lines. Since the Earth's magnetic poles are located relatively close to its geographic poles, a compass pointing to Earth's magnetic north pole also indicates the general direction of Earth's geographic north pole.
