Maglev
2014-04-11 09:17:26

Maglev is a vehicle propulsion system that uses magnetic levitation to move a vehicle with magnets instead of wheels. The vehicle hovers a short distance above the guide way by magnets and also uses the magnets for motion. The operation of this system is quite and maintains less friction for improved acceleration and deceleration. Weather does not affect the performance of the vehicle. Currently, some trains make use of the Maglev system, but vacuum tube trains could allow a Maglev system...

The Cathode Ray Tube, which has internal or external means to accelerate and deflect electron beams, is a vacuum tube containing an electron gun and a fluorescent screen. The electron beams that are deflected are used to create images in the form of light emitted from the fluorescent screen. The CRT works by using an evacuated glass envelope which is large, deep, heavy, and relatively fragile. Ferdinand Braun is credited with the first CRT in 1897. It can also be known as the Braun tube....

A tape drive is a storage device that reads and writes data on a magnetic tape. It is mostly used for offline, archival data storage. Tape media is generally cost efficient and has a long archival strength. In contrast to a disk drive which provides random access storage, a tape drive provides sequential access storage. This takes the tape drive a substantial amount of time between winding tape between reels and reading individual data, which is much longer than a disk drive. Consequently,...

An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...

A Radio Atmospheric signal (sometimes referred to as Sferic or Spheric), is a broadband electromagnetic impulse that occurs during atmospheric lightning discharges. Sferics spread out from the lightning source and can be received thousands of miles away. A sferic, depending on atmospheric conditions, may extend anywhere from a few kHz to several tens of kHz. Sferics from far reaching storms, over 1500 miles away, are generally offset in frequency range and may be picked up as tweeks. A...
