A new explanation has emerged for why Homo sapiens survived in Europe and North Asia when the apparently better-adapted ...

Ancient Homo sapiens may have benefited from sunscreen, tailored clothes and the use of caves during the shifting of the ...

For the first time, scientists have caught a glimpse of a strange and elusive creature in the world of quantum physics—a semi ...

Hans Fromme had found in Frankfurt that when he placed his European robins into a steel chamber and reduced the strength of the ambient magnetic field by a third, the birds' flutterings were no ...

the strength of the magnetic field increases; the length of wire inside the magnetic field is increased. The force is always greatest when the direction of the current is 90° to the direction of ...

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 ...

This means that the current to the external circuit is always in the same direction. increasing the rate of rotation increasing the strength of the magnetic field increasing the number of turns on ...
