"Magnetic sensors" refers to devices that can detect and measure magnetic fields. They are used to sense or detect objects or the presence of magnetic fields in different applications. Full definition
Interestingly the handset comes with magnetic sensors too, one would have assumed it to be missing considering the price tag. (gogi.in)
In the meantime, these unique magnetic structures can also be found on metallic surfaces, as used today in technological applications such as magnetic sensors or the reading heads of hard drives. (sciencedaily.com)
Researchers will probably also need to figure out ways to push higher electrical currents through the molecular wires to make magnetic sensors that can compete with current technology. (sciencemag.org)
