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 ...

As the number of turns increases the number of paper clips held increase. This means that the strength of the magnet increases with increasing number of turns in the coil. Once again, since the ...

Astronomers have finally unlocked a crucial piece of the planet formation puzzle by detecting the magnetic fingerprint of a young star’s protoplanetary disk. Using ALMA, researchers observed how dust ...

A double magnet cannon is put to the test against a towering structure crafted from magnetic balls. With incredible force, the powerful magnets unleash their energy, colliding with precision to ...

For the first time, astronomers have succeeded in observing the magnetic field around a young star where planets are thought ...

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 ...

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 ...

It is important to ensure that magnets are at the specified strength for their expected duty, in the right location, and positioned correctly in the process to ensure maximum product stream ...
