Measuring faint magnetic fields is useful in a number of areas, including mapping brain activity, monitoring hearts and probing fundamental physics. Typically, picking up such weak signals requires ...
A magnetic-levitation device can sort viruses and bacteria that naturally float in the air, making them ready for further analysis. Magnetic levitation is a method that uses magnetic forces to push ...
Scientists in Japan have developed a device that enables external magnetic field control of magnetic injection current in the bulk photovoltaic effect (BPVE), a phenomenon not yet used in commercial ...
