Although knowing all three vector components of a field provides more complete information about it, a truly scalar sensor ... broad dynamic range for the instrument, as the magnetic fields ...

Your own brain also emits tiny pulses of magnetic energy every time a neuron fires. But measuring what direction those fields are pointing, for precise atomic sensors in particular, can get tricky.

Yes, it will create an image of field lines coming out of a magnet, but it’s a very slow process. Instead of using just one magnetic sensor, [Peter] is building a two-dimensional array of ...

A pair of physicists at the University of Crete has found that some types of biological magnetoreceptors used by various creatures to navigate, operate at or near the quantum limit. In their paper ...

Sea turtles have earned their reputation as expert travelers, covering thousands of miles across open oceans with barely any ...

The CT455 sensor supports two standard field ranges, allowing it to sense and translate magnetic fields into a ... supports a preprogrammed 6 mT field range. Unlike other market solutions, our ...

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 ...
