This report is a compilation of considerations involved in the design of electro-magnetic rods for satellite erection. Formulae are derived showing the effect of various choices of core and wire material and weight, number of cores, length of cores, number of turns per core, and wire area on the magnetic moment, hysteresis power, hold power, hold voltage, and switching time. These formulae are then applied to the problem of producing a required magnetic moment at the least cost in weight and power consumption.
