The way Carlo Laj tells it, the 1980s were a dead time for scientists studying Earth's peculiar habit of flipping its magnetic field every few hundred thousand years. Laj and other paleomagnetists spent the decade roving the world, accumulating records of times when the magnetic field reversed...
(or power supply). if you have a high frequency current, the charge will be both added and taken away from the plates in the capacitor with no charge build up and the capacitor will act like it's not even there. what happens when you connect a capacitor and an inductor? suppose we ...
When compared to other ferromagnetic metals, titanium is weakly magnetic in the presence of a magnetic field. A specific effect is created with this metal. For example, a small electrical current will form in the metal when a magnet is passed over it. ...
Contrary to the popular belief, the best content doesn’t just come from good writing, but is also rooted in the amount of listening and learning that happens before the actual content is produced. Campbell Macdonald Campbell Macdonald is CEO and a Founder at Pathful which shows...
The foundation of many navigation systems, the World Magnetic Model finally got a much-needed update with the end of the U.S. government shutdown.
Radiation produces KE-heat (molecular motion) when it strikes matter, correct? So, if radiation entering a BH does not somehow get converted into matter, then it must increase the KE-heat inside the event horizon. The question is what happens to that KE-heat in a gravity situation that p...
What happens at if I look at an eclipse? Looking at a solar eclipse directly or without protection can cause "eclipse blindness" or retinal burns, which can damage or even destroy cells in the retina, negatively affecting your vision. Is it okay to look at a solar eclipse? No, it is ...
In a two-pole motor, if the electromagnet is at the balance point, perfectly horizontal between the two poles of the stator when the motor starts, you can imagine the rotor getting "stuck" there. That never happens in a three-pole motor. Each time the commutator hits the point where it...
What Happens During an MRI? You'll lie on a table that slides into the MRI machine. Straps might be used to hold you still during the test. Your body might be completely inside the machine. Or, part of your body may stay outside the machine. ...
The northern lights give us a unique window into our sun's activity, space weather and Earth's magnetic field. At any given moment, the sun is ejecting charged particles from its corona, or upper atmosphere, creating the solar wind. When that wind slams into Earth's ionosphere, or upper ...
