Your permanent magnet should lose no more than 1% of its magnetic strength over a period of 100 years provided it is specified and cared for properly. There are a few things that may cause your magnet to lose its strength: HEAT Heat above the maximum level rated for the magnet material in your separator [...]
X-Ray Diffraction Magnetic System Conduction-cooled (i.e. cryogen-free) magnets designed for x-ray diffraction measurements have the advantage of compact size compared to a conventional liquid helium system, permitting the assembly to be fitted to existing goniometers. A variable temperature insert, typically 2 to 300 K allows for sample rotation in the magnetic field. The system pictured [...]
Electromagnetic Sheet Fanners Electromagnetic Sheet Fanners eliminate die-damaging, double-blanking problems in automated sheet handling operations. A powerful electromagnetic field automatically separates the sheets. As fast as the top sheet is removed, the next sheet instantly moves up. The on/off capability of the Electromagnetic Sheet Fanners provide operator safety during steel blank stacking and un-banding. This [...]
Why compass can be inaccurate Compasses are brilliantly useful but they can sometimes lead us astray, because of two quite different problems called declination (or variation) and deviation. Here's why. compass Declination (variation) Earth spins about an axis (a kind of invisible rod) running through the north pole (sometimes called the geographic north [...]
North Magnetic Pole - "Magnetic North" redirects here. For other uses, see Magnetic North (disambiguation). The North Magnetic Pole is the wandering point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downwards (in other words, if a magnetic compass needle is allowed to rotate about a horizontal axis, [...]
Radical new maglev elevators that travel in ANY direction could lead to super skyscrapers far taller than today's buildings Technological innovations have allowed us to build skyscrapers to great heights But people still don't live in skyscrapers the way futurists had envisioned This is because elevators are only able to go up and down, and [...]
Test Tower for Futuristic Magnetic Elevators Nears Completion Elevators that can go up and sideways look set to be the way of the future thanks to German engineering firm ThyssenKrupp. ThyssenKrupp stated recently in a press release that after 10 months of construction they’ve almost finished building the exterior of a massive 761-foot concrete tower [...]
