It's not quite so easy to capture the magnetic field of the Milky Way though. The new method to measure the field relies upon the small dust grains which permeate space between the stars.

Using an XMC1100 microcontroller development board and a TLV49 3D magnetic sensor ... time and produce an approximation of what the field lines would look like on its electronic paper display.

Last year, [Ted Yapo] built a magnetic imager from a single magnetometer placed on the head of a 3D printer ... Yes, it will create an image of field lines coming out of a magnet, but it ...

and the cause of instabilities in the keyhole that leads to defects in 3D printed parts. The team then observed the manufacturing process with a magnetic field applied to the metal alloys as the ...

Some animals that migrate across the globe—such as birds, salmon, lobsters and sea turtles—are known to navigate using the magnetic field lines that stretch from Earth's north to south pole.

Excitons occur homogenously across typical 3D ... magnetic semiconductors. The two groups decided to compare notes, Shao said, and found that they all had come to the same conclusion. "Our data ...
