MAGPIE (Mega Ampere Generator for Plasma Implosion Experiments) is a pulsed power generator based at Imperial College London, United Kingdom. The generator was originally designed to produce a current pulse with a maximum of 1.8 million amperes in 240 nanoseconds (150 nanoseconds rise time). At present the machine is operated with a maximum current of approximately 1.4 million amperes and operates as a z-pinch facility.

MAgPIE is a non-linear, recursive, dynamic-optimization, global land and water-use model with a cost-minimization objective function. MAgPIE was developed and is employed by the land-use group working at the Potsdam Institute for Climate Impact Research (PIK). It links regional economic information with grid-based biophysical constraints simulated by the dynamic vegetation and hydrology model LPJmL. MAgPIE considers spatially-explicit patterns of production, land use change and water constraints in different world regions, consistently linking economic development with food and energy demand.

Magpies are birds of the Corvidae (crow) family, including the black and white Eurasian magpie, which is considered one of the most intelligent animals in the world, and the only non-mammal species able to recognize itself in a mirror test. In addition to other members of the genus Pica, corvids considered as magpies are in the genera Cissa, Cyanopica and Urocissa.
