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 ...

Repeated impacts can create minerals that lock in magnetic signals long after the Moon’s global field has disappeared.

Twentieth-century explorations answered many questions about our satellite and its place in the solar system. But they also raised many new and challenging questions that still remain unanswered. One ...
