A very preliminary proposal to make up a system that cancels the magnetic eld of Earth for executing satellite magnetic tests in Venezuela is made. Firstly, it is reviewed general satellite magnetic status considering electrical currents in it and possible magnetic domains in the structure and equipment is reviewed. After checking some magnetic cancellation systems, it is concluded that an optimal option to be selected is a Merritt 4-coil system because it offers good uniformity of magnetic field in a large relative volume. After some considerations and taking into account the usual size of a small satellite, the size of the coils should be around 32 meters. Finally, some considerations about the movement of the Earth’s magnetic poles are taken into account.Downloads
