The video explains the concepts of magnetic, electric, and gravitational fields using simple demonstrations. It shows how iron filings reveal the magnetic field around a magnet, how charged ...

There are two distinct cores – a solid "Inner" core and a molten "Outer" core. The inner core remains solid due to the immense pressures on the iron and nickel found there. So, the magnetic field that ...

Earth’s Northern Lights typically dance near the poles, but 41,000 years ago, they lit up skies over North Africa and Australia. New research reveals how dramatically Earth’s magnetic field weakened ...

Abstract: Optically pumped magnetometers (OPMs) operating in the spin-exchange relaxation-free (SERF) regime achieve excellent sensitivity in environments with zero magnetic fields. Therefore, it is ...

could be disrupting the flow of molten iron responsible for generating Earth’s magnetic field. The LLSVP sits about 2,900 kilometers (1,800 miles) beneath Earth’s surface, wedged between the ...

Scouts have routinely compared Milroe to current New York Jets starter Justin Fields. For a piece published Wednesday, ESPN's Ben Solak either intentionally or unintentionally hinted that how ...

Electric and magnetic fields are important factors to be considered when designing transmission lines. They occur in nature and have become much more prevalent in our everyday lives through man-made ...

Researchers are now advocating using electric fields to do this switching. For this, electric fields have an advantage, since they're more amenable to controlling magnetic devices than are ...

Unlike the fixed geographic North Pole, magnetic north is shaped by the movement of molten iron in Earth’s outer core. This churning metallic flow generates the planet’s magnetic field, a dynamic and ...
