Magnetic sensors - a new slant on an old technology

Dr. Paul Robertson and his team are working on a new slant to an old sensing technology. Flux-gate magnetic sensors have been around for many decades and are still used today for tasks such as geological surveys, aerospace instruments and even detecting submarines, as submarines disturb the Earth's magnetic field around them. These devices are usually quite large; assembled from coils wound on to magnetic cores.
