A wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new ...

If we could visualize Earth’s magnetic field, we would see that it is what we scientists call a dipolar magnetic field. This is where the lines of force leave one hemisphere and enter the other.

The Analyzer for Cusp Electrons (ACE) is designed to measure electron activity in the region of the northern magnetospheric ...

the angle at which magnetic field lines intersect the Earth. The turtles use these two pieces of information, which vary at every point on the planet's surface, as navigational markers that help ...

The compass needle points in the direction of the Earth's magnetic field ... direction each time join the points to show the field lines The needle of a plotting compass points to the south ...

Scientists have confirmed a 19-year-old theory on solar flare formation by observing “slip-running” reconnections in the ...

While shifting is not a rare occurrence, the pole is moving both faster and differently than it was before, raising questions about the planet's magnetic field. If the Earth's field is disrupted ...

A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...

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.

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 ...
