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.

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.

In magnetic reconnection, adjacent magnetic field lines break and snap together to form new lines. This process converts ...

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 ...

Simulations of highly magnetized stars that explode and collapse into black holes show that they transfer their magnetic fields to the disk of swirling matter that forms around the new black hole.
