A chance alignment of planets during a passing gust of the solar wind has allowed scientists to compare the protective effects of Earth’s magnetic field with that of Mars’ naked atmosphere. The result ...

This video explains how inductors work and how they store energy in a magnetic field when electrical current flows through them. Inductors are passive components used to resist sudden changes in ...

Scientists explain why there’s no merit to recent claims blaming Earth’s magnetic poles for global warming—and what those geomagnetic shifts really mean. A visualization of the magnetic lines of force ...
