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 ...

At ultracold temperatures, interatomic collisions are relatively simple, and their outcome can be controlled using a magnetic ...

If you need help visualizing magnetic fields, these slow-motion video captures ... The technique and equipment are simple and shown in the video. A layer of black sand is spread on a piece of ...

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 ...

One of the many unseen forces to which you owe your existence is magnetism. If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely ...

A team of researchers has created washable and durable magnetic field sensing electronic textiles - thought to be the first ...

Would a dramatic change in the Earth's magnetic field affect creatures that rely on it during migration? Late on a January night in 1993 I found myself on a beach on the Pacific coast of Costa ...

At ultracold temperatures, interatomic collisions are relatively simple, and their outcome can be controlled using a magnetic ...
