It looks the same as my older cow magnets but they do not have a magnetic field similar to a bar magnet. Rhett Allain is an associate professor of physics at Southeastern Louisiana University. He ...

"Changing position of the bar magnet varied the strength of magnetic field over 1-10G," Shaw said. "This observation in such a low range of magnetic field was surprising." ...

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, an ...

Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether ...

Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University Mainz have ...

Using this method, [efeyenice983] found that the Earth’s magnetic field strength at their location was about 0.49 Gauss, which is well within 0.25 to 0.65 Gauss that is typically found on the ...

The magnetic field lines of a bar magnet can be viewed by using compasses or by shaking iron filings onto a platform above the magnet. Details Equipment [1] Bar magnet [1] Shaker of iron filings [3] ...

The magnetic field in a permanent magnet does tend to decay over time, but not with a predictable half-life as with radioactivity. “Permanent” or ferromagnetic materials have tiny regions, or ...

Scientists have announced that they achieved the highest magnetic field strength ever recorded for an accelerator steering magnet, setting a world record of 14.1 teslas, with the magnet cooled to ...

If Earth’s magnetic field resembles that of a bar magnet, Jupiter’s field looks like someone took a bar magnet, bent it in half and splayed it at both ends. The field emerges in a broad swath ...
