Superleader Discovered by the physicists of Heike Kamerlingh Onnes in the year 1991, he had experimented with the measure of the electrical resistivity of mercury and found that when the mercury cooled down to a temperature of about 4.2 K or at-269 C °, the electrical resistance of mercury is gone into a superconductive leader. From then on. Scientists have been constantly researching and found that many metals have a superleading condition. When cooling down to one or lower temperatures, the The maximum temperature at which metals are still a superleading condition is about 20 K, which is also very low, scientists try to find a superleader at a higher temperature, especially at around 300 K, can now discover a superleader at a temperature of 98 K from a metal oxide called the "ceramic ", such as Strontium oxides, Uttrium, the temperature of 98 K can be controlled using liquid nitrogen, which is cheap. Typical applications are on the basis that "Superleader There is no electrical resistance, and there is a thrust on the magnet. "From this remarkable feature, we will see the Skytrain running in the big city, moving on over the rails on the magnetic field. It sees a smaller electric motor, but it is equivalent to a multi-horsepower engine, it sees smaller appliances, and it consumes less power, but is better or more efficient. The computer is smaller, but the process is much faster, and the more important it is to see the power transmission line in the road, it doesn't require a large line and a transformer to keep the baby in the eye.
