‘We’ve also built a coil like this under water before, where the field is changed to be like it would be in Northern America - then they can see changes in the sharks behaviour, so most definitely animals use magnetic fields for navigation. We’ve imported hundreds of these specific sensors, and we sell them to Denel, and they place them on some system that flies towards a target and goes kaboom at the end.

The Hermanus Magnetic Observatory also supplies one-minute data to the World Data Centre for Geomagnetism, Kyoto in Japan, for the generation of the Dst ringcurrent index, which is the most commonly used measure of geomagnetic storm intensity. *
The observatory is an active participant in the International Real-time Magnetic Observatory Network, one of a large number magnetic observatories which monitor and model variations of the Earth’s magnetic field. *

South Africa maintains a scientific base in Antartica where it is ideal to study the Southern Atlantic Magnetic Anomaly - covering an area where communication systems are more exposed and vulnerable to damages and interruptions caused by high levels of radiation from space. Together with the geomagnetic and auroral observation research done on the Antarctic, Marion and Gough Islands, SANSA Space Science promotes interest in science through science advancement programmes.
SANSA(South African National Space Agency) Space Science emerged from the original Hermanus Magnetic Observatory that was first established in 1941.
