An attempt was made to measure directly the line integral of the geomagnetic field around a closed circuit with an area of 3620km2. The intensity and direction of the horizontal component of the magnetic field were measured at 146 sites spread around the circuit, which was located near Carnarvon (Western Australia), where local irregularities due to crustal magnetism are small. The result is not significantly different from zero, but the uncertainty is larger than the average magnitude of curl B over the Earth, according to the recent world magnetic charts
