Earth - Wikipedia

Earth is the third planet from the Sun and the only astronomical object known to harbour and support life.About 29.2% of Earth's surface is land consisting of continents and islands. The remaining 70.8% is covered with water, mostly by oceans, seas, gulfs, and other salt-water bodies, but also by lakes, rivers, and other freshwater, which together constitute the hydrosphere.


Magnetic Separators. Cyclotron's magnetic power separators, model CTMD, efficiently filter particles as small as 25 microns from all ferrous swarf materials in water-based or synthetic oils requiring minimal electric power and no disposable filter media. Our magnetic separators are housed in high carbon steel with a raised pole design, using powder-coated steel components.

a bar magnet is moving toward a conducting loop with its north pole down, as shown in Figure 10.1.8(a). With the magnetic field pointing downward and the area vector A pointing upward, the magnetic flux is negative, i.e., G ΦB =−BA <0, where A is the area of the loop. As the magnet moves closer to the loop, the magnetic field at a point on the

Magnetic elements are typically assembled with a minimum of five magnetic poles that span an arc of 110 degrees. (For all practical purposes, an arc of only 80 degrees is required to impart a separation. Non-magnetic particles usually leave the drum surface with a natural trajectory at a point of 60 to 70 degrees from "top dead center ...
