Diamond dust enables low-cost, high-efficiency magnetic field detection

Engineers have created a device that dramatically reduces the energy needed to power magnetic field detectors, which could revolutionize how we measure the magnetic fields that flow through our electronics, our planet, and even our bodies. The researchers found a new way to excite tiny diamonds with microwaves using 1,000 times less power, making it feasible to create magnetic-sensing devices that can fit into electronics like cell phones.
