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

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… ...

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

A physicist explains. Magnets are "one of the deepest mysteries in physics," said Greg Boebinger, director of the National High Magnetic Field Laboratory in Tallahassee, Florida.

The three types of magnetism that occur in materials are diamagnetism, paramagnetism, and ferromagnetism. Whenever you apply an external magnetic field to a material, you’ll get one of the ...

This one-of-a-kind magnet can reach and sustain magnetic field strengths of up to 25 T in a completely resistive fashion -- in and of itself likely the most powerful solenoid on the planet.

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.

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 ...

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.

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.
