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

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.

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.

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 ...

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 magnetic field is thought to arise according to the so-called geodynamo model: the molten core’s movement gives rise to electric currents that in turn produce the magnetism of Earth.

Researchers have demonstrated that microscopic drug delivery containers can be magnetically steered to their targets, ...
