The world's strongest magnet isn't just science fiction: it's real, ridiculously powerful, and used in some truly fascinating ...

There's a magnet in a secure room in central Tokyo. It's an electromagnet, the kind that generates a magnetic field when ...

In medicine permanent magnets demonstrate unique advantages in terms of field strength, tunability of field and gradient distributions, and practical implementation. The findings highlight the ...

The miniature electromagnet was created by MagLab engineer Seungyong Hahn. It generated a world-record 45.5 tesla magnetic field — more than 20 times the strength of a hospital MRI magnet.

Today, manufacturing strong magnets is no problem from a technical perspective. It is, however, difficult to produce a permanent magnet with a magnetic field of a specific pre-determined shape.

This movement produces an electrical current that generates and maintains the strong magnetic field around the planet. The field has two opposite poles located at the north and south of the planet, ...

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform ...

That magnet, because it was a normal copper conducting magnet, consumed approximately 200 million watts of energy to produce the confining magnetic field.

Magnetic effect without a magnet Date: February 22, 2021 Source: Vienna University of Technology Summary: Electric current is deflected by a magnetic field -- this leads to the so-called Hall ...

The traditional method for visualizing magnetic fields, which your science teacher probably demonstrated at some point, is to sprinkle some iron filings onto a piece of paper and hold it over a mag… ...

The magnetic field used in the experiments was about the same as a regular fridge magnet, which is much stronger than the Earth’s natural field.

The new look at Jupiter’s magnetic field comes courtesy of NASA’s Juno spacecraft, which has been orbiting the planet since July 2016 (SN: 6/25/16, p. 16).
