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 Daycare The Longest Daycare Maggie Simpson in "The Longest Daycare", or simply The Longest Daycare, is a 2012 American traditionally animated 3D comedy short film based on the animated television series "The Simpsons". In the film, Maggie Simpson is enrolled at a new daycare facility where she squares off with the foul-tempered Baby Gerald when she befriends a caterpillar. The short originated with "Simpsons" producer James L. Brooks, who enlisted long-time veteran of the series, David Silverman, to direct the film.
