WebMaglev (derived from magnetic levitation), is a system of train transportation that uses two sets of electromagnets: one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction.Such trains rise approximately 10 centimetres (3.9 in) off the track. There are both high speed, intercity … WebLasers operate on two general principles: light amplification using a gain medium (e.g. Ti:sapphire crystal) and feedback ensured by a cavity (e.g. two mirrors). As light is amplified in the excited gain medium, an intense laser beam is produced due to the feedback of the cavity, which is partially transmitting ( Figure 1 ).
