Iron particles effectively act as tiny magnets that can record both magnetic field strength and direction when the process of crystallization locks them in place. The researchers found that rocks ...

The study, published in Nature Communications, uses a method called synchrotron intensity gradient (SIG) to map magnetic fields in clusters, especially during galaxy mergers. This method provides ...

Scientists in China have developed the world’s strongest resistive magnet, which produced a steady magnetic field of 42 Tesla ...

Relative field strength is indicated by the size of the ... visualizing complex magnetic fields and more than two poles would take an array of sensors and likely a more powerful processor.

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 ...

These are common minerals found in Earth’s crust, which preserve the record of our planet’s magnetic field strength. The team ...

Magnetometers and Gaussmeters are sometimes used interchangeably for describing devices used to measure magnetic field strength. However, the two can be differentiated based on the type of field ...

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 ...

A coil with an iron core is called an electromagnet. The iron core increases the coil’s magnetic field strength. A simple electromagnet is made by coiling wire around an iron nail. An iron core ...

Allowing for the changes, this key component of Atlantic heat transfer appears to be much more robust than previously thought ...

The outburst can interfere with power grids and cause blackouts, as well as fry satellites and interfere with GPS ...

Scientists have directly mapped the strength of the magnetic field of the solar corona — the outer part of the sun’s ...
