The NMR phenomenon relies on the interaction of the nuclei of certain atomic isotopes with a static magnetic field. This magnetic field makes the possible spin-states of the nucleus differ in energy, ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...

Electrets produce a semi-permanent static electric field, similar to how a magnet produces a magnetic field ... He built a simple electric field detector, which is just a battery, LED and FET ...

The Kenyan group analyzed the performance of a multicrystalline solar panel influenced by a static magnetic field they calculated was the equivalent of the ‘geomagnetic field’ which protects ...

Scientific discoveries often come from connecting the dots between ideas that seem completely unrelated. A research team at ...
