China's Chang’e-6 mission has delivered the first-ever samples from the Moon’s far side, shedding light on one of planetary ...

The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from. But new research suggests they ...

In this informative video, discover how to make a magnet generator to light bulbs efficiently. We guide you through each step ...

Dive into the exciting world of magnetic energy with our latest experiment focusing on motor-generator systems! In this video ...

Once upon a time, Mars had a magnetic field, just like Earth. Four billion years ago, it vanished, taking with it the planet’s chances of evolving life as we know it. Now scientists have ...

Some exoplanets in their stars' habitable zones may be distinctly uninhabitable due to solar flaring. Red dwarfs are known for powerful flaring, and since they're dim and their habitable zones are ...

Within an existing magnetic field, a dynamo acts as an electrical generator to induce an electrical current in the flowing iron. This action produces its own magnetism, which strengthens and ...

Or perhaps there is no need for the presence of a dynamo-driven magnetic field at all. For instance, the authors of a 2021 study thought earlier analyses of lunar samples may have been altered ...

Both the lights and the dynamo are IP67 dust- and water-resistant, and are permanently installed via a reportedly quick and easy process. Buyers can pick and choose the bits they want, with a ...

A low magnetic Reynolds number means that the dynamo is weak and could soon dissipate. A high number means that the dynamo is powerful. Earth’s magnetic Reynolds number is on the order of 1000.
