We Earthlings see the sun every day of our lives—but gaining a truly new view of our star is a rare and precious thing. So ...

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 ...

As you may recall from Physics 101, a changing magnetic field (like when you slide a bar magnet through a copper coil) induces an electric current. At planetary scale, Earth’s magnetic field induces ...

The maximum field tolerance of these MRAM devices is between a few tens of milliTesla, mT, to 100mT, depending upon the MRAM target application. 10mT in SI units is 100G in CGS units of magnetic ...

Image credit: Andrew Z. Colvin, CC BY-SA 4.0, via Wikimedia Commons Our planet’s magnetic field is similar to that of a bar magnet in that it has a north and south pole, but it is far less stable.

Any moving electric charge creates a magnetic field around it. A loop of wire with a current creates a magnetic field through the loop. You can increase the strength of this field by piling up a lot ...
