The shift in polarity marks the point at which the sun is halfway through solar maximum, the height of its activity, and the beginning of the shift toward solar minimum. The sun's magnetic field ...

Researchers from the Department of Physics have managed to experimentally develop a new magnetic state: a magneto-ionic ...

But now it works great, and [EmGi] even deposited an array of 64 magnets without using glue to test it out before printing a second one to handle the other polarity. Check out the build/demo video ...

As there-could be no magic in the case, it appeared that the balance had magnetic polarity, as no other cause could produce the effect I had witnessed, and which was repeated as often as I chose ...

As the time line at right shows, hundreds of times in our planet's history the polarity of the magnetic shield ensheathing the globe has gone from "normal," our current orientation to the north ...

The flip-dot is controlled by an array of neodymium magnets with the proper polarity to flip the segments to the desired number. The magnets are attached to an aluminum disk, with each array ...

Have you ever played with a magnet and stuck it in a sandy wash? It will pick up lots of black stuff. Some call it black sand; some might think ...

One of the many unseen forces to which you owe your existence is magnetism. If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely ...

This method uses the orientation of the Earth's magnetic field, which has changed through time, to determine ages for fossils and rocks. Relative dating to determine the age of rocks and fossils ...

using a gigantic magnet, can line up the protons -- or nuclei of hydrogen atoms -- in an object (or organism) to align with the north-south polarity of the magnet. A computer "reads" this to ...

This localized heating temporarily reduces the coercivity of the recording material, enabling the write head to alter the magnetic polarity of a single bit at a time. By allowing data to be ...
