A wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new research has presented experimental evidence confirming a previously theorized ...

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 ...

This device varies magnetic field intensity by rotating a single magnet about two axes at the same time. This could be a legitimate, real invention, if only it were claimed as a human amusement device ...

Since electronic equipment has been more sophisticated and versatile recently, highly operable input devices are required. We introduce some rotating devices (jog mechanism) using Hall effect ICs here ...
