Figuring out the ages of stars is fundamental to understanding many areas of astronomy—yet, it remains a challenge since ...

Magnetic Group forecasts a pivotal shift in the aircraft engine market, with key trends signaling an approaching inflection ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth.

When summer comes knocking hard, an air cooler is like a part of your everyday life. It’s the cost-effective version of air conditioning, cooling you down without breaking the bank on your electricity ...

However, when a rotating magnetic field is introduced, the rolling flow competes with and can eventually overpower the spontaneous propulsion. The researchers found that at 20 Hz, the droplet ...

In an induction motor, the current in the stator windings generates a rotating magnetic field, which induces current in the rotor and causes it to spin.

And Jupiter, having recently finished its phase of ravenous gas accretion, was undergoing a dramatic transformation. According to Batygin and Adams, Jupiter’s radius at that time was between 2.0 ...

The magnetic flux density, angular frequency and rotation axis can be modulated by tuning the amplitude and frequency of each phase current. The device can achieve a rotating magnetic field with ...

The Voyager spacecraft discovered that the ice giants Uranus and Neptune have nondipolar magnetic fields, defying expectations that a thick interior layer of planetary ices would generate strong ...
