The Equator
Agonic Line
the prime meridian
It depends on which line you are talking about. It may be the International Date Line,or maybe you meant east to west, so then it would be equator. But for now, it wouldbe the lines of longitude.The imaginary straight line that connects the north pole and south pole directlywithout staying on the surface is the Earth's rotational axis.

-- Most of the imaginary lines on the surface are parallels of latitude, meridians of longitude, political boundaries, and shipping routes. -- The imaginary lines through the center of the globe are the axis and diameters.
no, a closed system is means if whats inside it remains as it is same as a closed surface, magnetic flux stays in place.

The imaginary line that extends straight out from the center of a reflective surface is the optical axis.
A constellation has no surface, it is an imaginary pattern of stars.
These magnetic disturbances are known as magnetic storms.

Magnetic flux through a surface is maximum when the direction of the magnetic field is in the same direction as the normal vector of the surface. In other words, the magnetic flux is maximum when the magnetic field is perpendicular to the surface area. That's why φ=BAcosθ, where θ is the angle between the direction of the magnetic field and the normal vector of the surface area. When the magnetic field is exactly the same direction as the normal vector (aka the magnetic field is perpendicular to the surface), θ=0 and cosθ = 1, its maximum value. The closer θ is to 90 degrees (ie. the more parallel the direction of the magnetic field is to the surface area, or the less parallel the magnetic field is to the surfaces normal vector), the smaller cosθ is, and thus flux will decrease accordingly.

By changing the permiability of ferromagnetic meterials, surface and near surface discontinuities are traced, is the principle of magnetic particle testing.
