When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right ... and generators to operate. In the Earth (see image below right), the ...

If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely have little atmosphere to speak of. Life (at least of the human variety) ...

This dynamic movement generates Earth's magnetic field, a protective shield against harmful solar radiation and cosmic particles. This magnetic field also influences plate tectonics and mantle ...

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 ...

Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...

"This speed – alongside the weakening of Earth's magnetic field by around nine per cent in the past 170 years – could indicate an upcoming reversal," said Cooper.

New research sheds light on the Earth's "innermost inner core," offering new insight into the formation of the planet and its magnetic field. From our morning news briefing to a weekly Good News ...

The phase diagram shows the state ... and is thus able to generate magnetic fields (red dotted area). For comparison: At the core-mantle boundary of the Earth at a depth of approx.

This "nano-compass" allows the microbe to passively orient itself in Earth's geomagnetic field (Figure 2). These magnetic nanoparticles ... concentration (top of the diagram) swim forward to ...
