This video provides a clear explanation of inductors and their role in electronic circuits. Inductors are passive components ...

The Earth’s magnetic field plays a big role in protecting people from hazardous radiation and geomagnetic activity that could affect satellite communication and the operation of power grids. And it ...

In a remarkable leap for quantum physics, researchers in Japan have uncovered how weak magnetic fields can reverse tiny ...

A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new insights into its future. Earth benefits from the presence of a magnetic field ...

Every so often—every 250,000 years on average—the Earth's magnetic poles reverse polarity. If such a reversal happened today, compass needles would point south rather than north. Here, view a computer ...
