An electromagnetic coil (the first lens) concentrates the electrons into a more powerful beam. Another electromagnetic coil (the second lens) focuses the beam onto a certain part of the specimen. The specimen sits on a copper grid in the middle of the main microscope tube. The beam passes th...

It took a few decades for Edwin Hall's revolutionary discovery to catch on, but now it's used in all kinds of places—even in electromagnetic space rocket engines. It's no exaggeration to say that Hall's groundbreaking work has had quite an effect! Artwork: How a typical Hall sensor is...
Also, in which region of the electromagnetic spectrum is this line observed? What happens in the emission spectrum when a photon returns to a lower energy level or the ground state? How can the frequency of emitted light be used to determine the energy difference between electron levels? How ...
We propose a mechanism to explain the low-frequency QPOs observed in X-ray binary systems and AGNs. To achieve this, we perturbed stable accretion disks ar

DICS beamforming: Power in the individual α-band (IAF ± 2 Hz) was projected into source-space using a DICS beamformer42utilizing all 306 (magnetometer and gradiometer) channels. A common spatial filter was computed from the averaged cross-spectrum in the IAF band across all segments ...

Since radio waves are part of the electromagnetic spectrum, they travel at the speed of light (300,000 km/second or 186,000 miles/second), so the waves are picked up almost instantaneously by the other handsets. The radio waves are converted back into fluctuating electric currents and the ...
