Dipole model of the Earth's magnetic field (MLAT), or geomagnetic latitude, formula_10 is measured northwards from the equator (analogous to geographic latitude) and is related to formula_9 by formula_12. In this case, the radial and azimuthal components of the magnetic field (the latter still in the formula_9 direction, measured from the axis of the north pole) are given by formula_14 formula_15 formula_16 where formula_17 in this case has units of Earth radii (formula_18). Invariant latitude is a parameter that describes where a particular magnetic field line touches the surface of the Earth. It is given by formula_19 or formula_20 where formula_21 is the invariant latitude and formula_22
The Longest Journey The direct sequel to "The Longest Journey", entitled "The Longest Journey Home", was revealed in 2013 and is to be produced after "Dreamfall Chapters". By 2016 the release of TLJHome is still under a question. Ragnar Tornquist stated that even though he wants to produce the game, there are many and many reasons why it may never happen. The Longest Journey The Longest Journey () is a point-and-click adventure video game developed by Norwegian studio Funcom for Microsoft Windows and released in 1999. The game was a commercial success, with sales in excess of 500,000 units by 2004, and was
