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 ...

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 ...

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 ...

New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...

As you may recall from Physics 101, a changing magnetic field (like when you slide a bar magnet through a copper coil) induces an electric current. At planetary scale, Earth’s magnetic field induces ...

When charged with 1,168 A, the coil generated a magnetic field with a strength of 7.3 Tesla (T), about 7,000 times the strength of a refrigerator magnet.
