Likewise, a wire passing through a magnetic field creates an electric current within the wire. This is the basic principle that allows electric motors and generators to operate. In the Earth (see ...

Nearly two centuries after Faraday's failed attempts, scientists have demonstrated that Earth's continuous spin can directly ...

American researchers have measured a tiny electrical voltage by exploiting Earth's magnetic field in the planet's rotational motion. This discovery, though modest, revives a scientific debate ...

Would a dramatic change in the Earth's magnetic field affect creatures that rely on it during migration? Late on a January night in 1993 I found myself on a beach on the Pacific coast of Costa ...

Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the aurora-causing effects of the solar wind. However, towards the equinox, the two fields ...

From there, the other directions can be figured out. Without the Earth’s magnetic field, this useful phenomenon would not occur. Whilst the geographical and magnetic north poles aren’t always ...

The compass needle points in the direction of the Earth's magnetic field, or the magnetic field of a magnet. place the plotting compass near the magnet on a piece of paper mark the direction the ...

Creatures from migratory eels and other fish species to insects to birds tap into the Earth’s magnetic field to navigate, sometimes many thousands of miles. But so far, evidence has been scant for any ...

When the Earth’s magnetic field is strong, as it is today, the amount of carbon generated by this interaction is relatively low, but it spikes when the magnetic field weakens and allows more ...

made the very first direct observations of a crucial hookup between the magnetic fields of the sun and the Earth. Called reconnection, this linkage is an important aspect of the transformation ...

Funding sources: $50K (2018-2021) from NSF Statistics Program PI: Tomoko Matsuo (CU-Boulder) Collaborators: University of California at Davis, NOAA NCEI Societal relevance: An accurate modeling of the ...

Now, though, a controversial new paper warns that falling space junk could actually weaken Earth’s magnetic field. If that happens, the author of the paper argues that we could see atmospheric ...
