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
Dell Latitude related to the 1100,5100,and 5150. The Latitude 110L is a near-clone of the Inspiron 1000. Dell Latitude Latitude is Dell's business laptop brand, designed and manufactured mainly by Compal and Quanta. The Latitude competes with the ThinkPad series from Lenovo (formerly IBM), the EliteBook series from HP and Travelmate series from Acer. The "Rugged (Extreme)", "XFR" and "ATG" models compete primarily with Panasonic's Toughbook line of rugged computers. The Dell Latitude is a laptop family from Dell Computers, intended for business use. By contrast, the Dell Inspiron is aimed at the consumer market and its specifications change regularly. Whereas Inspiron
