In this video, we'll learn about the reasons why transformers make a humming noise. We'll explore the physics behind the sound, and how transformers work.

Scientists Michael Hesse and John Dorelli explain the science objectives of the MMS mission.



The Magnetospheric Multiscale (MMS) mission is comprised of four identically instrumented spacecraft that will use Earth’s...

A special type of aurora, draped east-west across the night sky like a glowing pearl necklace, is helping scientists better understand the science of auroras and their powerful drivers out in space. Known as auroral...

NASA scientists answer some common questions about the sun, space weather, and how they affect the Earth. This is a two-part series.

It's hard enough to build one spacecraft, but the Magnetospheric Multiscale Mission (MMS) is building four. Together, the spacecraft will unlock the mysteries of magnetic reconnection, when magnetic fields explosively connect and...

Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection (CME), and some with complex moving structures in...

NASA is getting ready to launch a new mission, a mission to observe a largely unexplored region of the solar atmosphere that powers its dynamic million-degree outer atmosphere and drives the solar wind.



In late June...

NASA Scientist Dr. Holly Gilbert discusses the upcoming launch and overview of the MMS Mission.<b<b<br/>r/>r/>

Writing in the Geophysical Research Letters, NASA says a review of Voyager 2’s old data from 1986 showed that Uranus vented a giant blob of gas into space. <br/>

In March 2015, NASA will launch four identical spacecraft to study how magnetic fields around Earth connect and disconnect, explosively releasing energy -- a process known as magnetic reconnection.



The Magnetospheric...

This nugget explains the source, generation, properties and discovery of electromagnetic waves.

Sunspots have fascinated sky gazers through the ages. Now state-of-the art telescopes combined with the muscle of a supercomputer called ""Bluefire"" are allowing scientists to accurately model these mysterious structures, and unlock...

How an 8000V electromagnet can be used to shrink a quarter. The interplay between electric and magnetic forces leads to the Lorentz Force and Faraday’s law of induction which can be used to shrink a quarter, or any other type of metal coin.

Magnet paper or magnet film shows you where magnetic fields are. With MKBHD, Dianna explores how magnetic paper works, what devices look like with the paper, and a mystery magnet.

What did the Hubble telescope notice about Neptune? What are the layers of Neptune made of? What is similar and different about Neptune and Uranus?<br/>

A new study using observations from NASA's Fermi Gamma-ray Space Telescope reveals the first clear-cut evidence that the expanding debris of exploded stars produces some of the fastest-moving matter in the universe. This...

Learn about the different types of radiation in this physics video from the virtual school. Alpha particles, beta particles and gamma rays... what are they and how do they differ?



Introducing 'Alpha Man', 'Beta Boy' and 'The...

This video explains the structure and action of a transformer. The video discusses the two types of transformers, step up and step down, and provides examples for each. The video then goes into detail about the structure of a transformer...

The Ampere-Maxwell Equation we see a changing electric field leading to a circulating magnetic field, which is nearly a mirror of Faraday's law. The main idea of the Ampere-Maxwell Equation is that an electric current or changing...

Scientists say they’re finding clues that support a theory that the early moon and Earth’s magnetospheres combined <br/>

The video is a lecture on electric motors, covering how a current carrying conductor placed in a magnetic field can cause rotation due to the motor effect, which is the force experienced by a current carrying wire in a magnetic field....

Ongoing geomagnetic storms have led to sightings of the Northern Lights across North America this week, the result of a coronal mass ejection from the Sun that occurred on Sunday, sending a stream of charged particles toward Earth.
