In a nutshell Mars likely never developed a solid inner core during its early history, meaning its magnetic field was generated by a fully molten core, unlike Earth’s layered core structure.

Two German physicists have unveiled a compact magnet layout that outperforms the famed Halbach array, delivering stronger, ...

O'Neill's map shows that indeed the magnetic-field lines do coincide with large sites of star formation on the surface of the Local Bubble, such as the Orion Molecular Cloud that is home to the ...

Take magnetic fields – iron filings on a card will give you a 2D model, but a 3D visualization of the field would be much more revealing. For that job, this magnetic field following 3D carving ...

3D printed nanomagnets unveil a world of patterns in the magnetic field Date: December 20, 2021 Source: University of Cambridge Summary: Researchers have created DNA-like magnetic nanostructures ...

Principal investigator Giuseppe Schettino and colleagues used their 3D scaffold model to investigate the response of pancreatic cancer cells to radiation in combination with a static magnetic field.

But external magnetic fields would be able to distort the fields inside the hose. To look like a wormhole, the tube itself had to be made invisible. “We needed to make a 3D magnetic cloak to ...

However, the new magnetic wormhole funnels the magnetic field from one side of the cylinder to another so that it is "invisible" while in transit, seeming to pop out of nowhere on the exit side of ...

Geophysicist Daniel Lathrop wants, among other things, to use it to predict when the Earth’s magnetic field will next reverse. ... With the sphere spinning at 45 miles per hour, ...
