define of magnetic meridian
Answers
Explanation:
line on the earth's surface approximating a great circle passing through the north and south magnetic poles.
The magnetic meridian is an equivalent imaginary line connecting the magnetic south and north poles and can be taken as the horizontal component of magnetic force lines along the surface of the earth. Therefore, a compass needle will be parallel to the magnetic meridian.
The magnetic meridian at a station on surface of the earth is the (imaginary) line of intersection of a (imaginary) plane passing through the magnetic North and South poles of the earth with its actual surface.
Magnetic Meridian : A vertical plane passing through the magnetic axis of a freely suspended magnet is called magnetic meridian. Geographical meridian : A vertical plane passing through a place and geographic north and south axis is called geographic meridian
The magnetic equator is defined as the line around the earth where the magnetic field is horizontal, or parallel to the earth's surface. It does not circle the earth as a smooth line like the geographic equator, but instead it meanders north and south, as shown.
The Prime Meridian divides the Earth into East/West from the North Pole to the South Pole with an imaginary line along the longitude line of 0°. The Antimeridian, at 180° longitude, connects with the Prime Meridian to form a 3D giant circle all around the Globe, dividing it into Eastern and Western hemispheres.
