When we think of powerful magnets used in particle accelerators or for NMR (nuclear magnetic resonance), we often envision bulky machines, sometimes the size of buildings. But in an extraordinary ...

Scientists in the United States have created a small device that produces a tiny electrical signal from Earth’s natural rotation. Although the voltage is extremely small, the experiment shows that ...

In brief: A team of physicists believe it may be possible to harvest electricity using Earth's rotation through its own magnetic field, and they've published a paper involving a test that appears to ...
