Why does a current-carrying wire produce a magnetic field? Why might unmasked and masked air conduction thresholds be different? Why does a wire move in a magnetic field? Why is copper used for most electrical wiring? Why is it important for people to avoid electric shocks?
Flywheel energy storage devices turn surplus electrical energy into kinetic energy in the form of heavy high-velocity spinning wheels. To avoid energy losses, the wheels are kept in a frictionless vacuum by a magnetic field, allowing the spinning to be managed in a way that creates electricity ...
The end of Mars' magnetic field NASA/GSFC The event that set the Martian climate on its inexorable course to becoming the dry, dusty world it is today was the cooling of its metallic core and the subsequent death of its magnetosphere. Mars' small size and distance from the sun meant that...
