It’s thus worth putting in the effort to make a better antenna, and if you’re not fortunate enough to have a lot of space, your best choice may be a magnetic loop. [Robert Hart] takes us ...

The magnetic field is strongest at the center of the loop and weaker farther away, following an inverse square law. Outside the loop, the magnetic field resembles that of a dipole, with field ...

The ominous black square on the surface of the ... Bright coronal loops trace out loops in the magnetic field as magnetic particles spin along the loop from August in extreme ultraviolet light ...

Zoom out until you see most of the inside of the I-465 loop around Indianapolis ... they are instead oriented toward "magnetic north," and streets outside the 4-square-mile donation were built ...

So hacker of note and dedicated amateur radio operator [Jeri Ellsworth (AI6TK)] has started a video series devoted to building a magnetic loop antenna for the 160- and 80-meter bands. The first ...

Researchers at the Technical University of Denmark in Lyngby have converted the radiofrequency signals from Earth’s magnetic field into sounds ... sounds in Solbjerg Square in Copenhagen ...

Earth's magnetic field plays a vital role in everything from animal migration to protecting the Earth from the Sun's harsh solar wind. Now, a recent study finally sheds light on how some birds ...

The Earth's magnetic field is essential to life as we know it. But it’s something we can never see – or hear, until now. In a recent study released on Oct. 10 by the European Space Agency ...

Paper 403: Measuring magnetic loop antenna performance. Despite the advent of the internet and streamed services, there is still an interest in traditional broadcasting. With that interest comes a ...
