To understand the answers to these questions, it helps to have a basic definition of a magnet. Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt. The magnetic field
The narrow end of the cone is connected to the voice coil. The coil is attached to the basket by the spider, a ring of flexible material. The spider holds the coil in position, but allows it to move freely back and forth. Some drivers have a dome instead of a cone. A dome is jus...
The electromagnet is positioned in a constant magnetic field created by apermanent magnet. These two magnets -- the electromagnet and the permanent magnet -- interact with each other as any two magnets do. The positive end of the electromagnet is attracted to the negative pole of the permanent ...
Since we were careful to make the last point the same as the first, there is no ambiguity as to what should get filled in. Here we have something that looks like a yield sign restructured by a driver who did not, in fact, yield: Again, we can freely mix uppercase and lowercase lett...
However, when applied to freely flying wandering albatrosses, this refinement did also not interfere with their homing abil- ity [44]. Despite this, in more controlled experiments where a species of songbird did not move freely, it was demonstrated that magnets fixed on the bird's heads have...
Aliens with working visa are issued Alien Certificate of Registration I-Card (ACR I-Card) which will allow them to freely travel abroad and return to the Philippines. Once issued with the ACR I-Card, they are required to pay the exit/airport clearance fees in the amount of Php2,170 ...
Just like CCD cameras they are sensitive to IR radiation [23]. In addition they have a high dynamic range [28], i.e. very bright objects and very dark objects can be recorded satisfactorily at the same time. CMOS cameras have disadvantages as well. Because each pixel comes with a piece...
field between the negatively charged clouds and the positively charged Earth. When the electric field becomes strong enough—we're talking tens of thousands of volts per inch—the air becomes ionized, which means the electrons in the air can move more freely and are able to conduct electricity....
Clear acrylic and magnets doing odd things do indeed instantly start somered flags wavingamong those of us who're accustomed to independent thinkers likeSteornwho, as you say, claim to break the laws o' physics but never quite manage to actually do it. But Correlated Magnetics are not in th...
are also excellent candidates for gated content. Gating content like comprehensive guides, ebooks, or webinars that dive deep into a topic can be a great idea. People are more willing to share their info for valuable, in-depth resources. Often, these are offered as downloadablelead magnets. ...
