It is saddening to report that physicists in the United States have claimed to have found some errors in the superconductor theory. The overall use of trapped field magnets (TFM) is thought of to be impractical.
The superconductor theory was accepted by the science community over more than 50 years ago. This is ever since a General Electrics Scientist developed his critical state model. Now the University of Houston Physicists have reported finding a flaw within the theory that differs in their studies.
The general idea of superconductors is to present zero resistance to electrical circuits, and storing energy for long periods of time. The ones that store magnetic energy — known as being trapped field magnets — can actually behave like a super strong magnet.
The original theory was developed by a Scientist named C.P. Bean. He founded that the performance of a device is based on magnets and improves as the strength of the magnet increases. This remains true to the square of the increase. An example of this if the magnet is three times stronger, the device will perform up to nine times better.
Yet Roy Weinstein and his colleagues have found a key problem in the theory. This was mainly in the spatial distribution of field increases appear way more immediate than Bean originally thought at first.
Controllable and Repeatable
Roy Weinstein said:
Great increases in field occur suddenly, in a single leap, whereas Bean’s model predicts a steady, slow increase.
His findings is showing that this unexpected behavior produces controllable and repeatable results.
For them to reach the superconductor level, the pulsed field requires to be typically more than 3.2 times as strong as the TFM’s field is. Roy said with the latest findings that him and his colleagues produced, a rate of only 1.0 is all that is needed.
In terms of practical application for their discovery, the researchers are suggesting the ability to replace a $100,000 low-temperature superconducting magnet in a research X-ray machine with just a $300 TFM. Even or possibly replace a motor with one that is a quarter of the size of an existing one.
Elsewhere in the field, researchers are working on ways to create superconductors at even higher temperatures than the accepted -135ºC have made a breakthrough.
A Research Team even discovered that only only half the atoms in some iron-based superconductors are magnetic, giving us an even clearer understanding of how magnetism works in general.
