Imagine crossing vast oceans, soaring across continents, or tunneling deep beneath the earth—without ever getting lost. For ...

Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) have developed an innovative method to study ultrafast magnetism in materials. They have shown the generation ...

You can check this by placing the compass next to the bowl. The needle is being affected by the Earth’s magnetic field. One end points towards magnetic north and the other end points south.

Imagine waking up one morning to a world where compasses point south instead of north, where auroras shimmer across the ...

Primarily, the compass was used for geomancy for a long time before it was used for navigation Ancient Chinese alchemists realized that the magnetite ore would point towards a magnetic north. Their ...

As Ron Merrill, a magnetic-field specialist at the University of ... So hang on to your compass. For the foreseeable future, it should work as advertised.—Peter Tyson ...

Magnetic fields are fundamental to controlling the magnetization of materials. Under static or slowly varying conditions, a material's magnetization aligns with the external field like a compass ...

Would a dramatic change in the Earth's magnetic field affect creatures that rely ... So they can sense it, but can they use it like we do a compass, to orient themselves? In another experiment ...

How a tokamak works: The electric field induced by a transformer drives a current (big red arrows) through the plasma column. This generates a poloidal magnetic field that bends the plasma current ...
