On the Future Development of geomagnetism in Brazil

Naoshi Fukushima

Abstract


From the geophysical standpoint, in particular with respect to geomagnetism, Brazil is a country full of important and interesting tasks to deal with. Brazil has both the geographic and magnctic equator (unique in the rvorld), and the intensity of the geomagnetic held is the wcakest over the entire earth. The world community of geophysicists has appreciated very much the great effort of Brazilian suveyers (belonging to Observatório Nacional) to tracc the secular
vanation of the geomagnetic held in the past since the middle of the l9th century, in particular the rapid shifting of the magnetic equator along the eastern coast of Brazil.
