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
magnetic variation
Magnetic north refers to the point on the Earth's surface where its magnetic field points vertically downwards, which is influenced by the Earth's magnetic field and can shift over time. Rotational north, or true north, is the direction along the Earth's surface towards the North Pole, where the Earth's axis of rotation meets its surface. The difference between the two is known as magnetic declination, which varies by location and affects navigation using compasses. In summary, magnetic north is based on the Earth's magnetic field, while rotational north is a fixed geographical reference.
The Greenwich Meridian, also known as the prime meridian or International Meridian, bisects the primary division of time zones. Each time zone is 15 degrees of longitude in width, with local variations, and observes a clock time one hour earlier than the zone immediately to the east. The time difference between two meridian lines is one hour (the time difference between two longitudinal lines is 4 minutes and consequently the time difference between 15 longitudinal lines; or two meridian lines; would be one hour). Refer to link below.The Greenwich Meridian bisects the primary division of time zones. Each time zone is 15 degrees of longitude in width, with local variations, and observes a clock time one hour earlier than the zone immediately to the east. The time difference between two meridian lines depends on where you draw the lines. There is no official standard set of lines that everyone is required to use, and a line can be drawn at ANY longitude. Whatever the longitude difference is between the two meridians you decide to consider, the time difference between them (in hours) is nominally 1/15 of that angle.
Approximately 5000 years ago, magnetic north and geographic north were not aligned as they are today. The difference between the two, known as magnetic declination, would have varied depending on the specific location, but it could have been several degrees. This variation is due to changes in the Earth's magnetic field over time.
The Urals. They are generally considered to be the dividing line between Europe and Asia.
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.
the magnetic north pole moves while the geographic north pole stays in the same place

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.

The main difference between the eastern and western hemispheres is their geographical location. The eastern hemisphere includes parts of Africa, Asia, Europe, and Australia, while the western hemisphere includes parts of North and South America. Additionally, the eastern hemisphere is often associated with older civilizations and cultures, while the western hemisphere is known for its more recent history of colonization and globalization.
