Superconductivity is a compound, element, or alloy that can conduct electricity without resistance below a certain temperature. Resistance is not desirable because it produces less current flow through the material. Discovered in 1911, by Dutch physicist Heike Kamerlingh Onnes, superconductivity was introduced. Onnes discovered certain materials when cooled had zero electrical resistance, and expulsion of magnetic fields.
Superconducting magnets provide conventional energy transportation. The magnets create an invisible force that make applications “float”. Countries like Japan, and England already have “floating” train transportation. The United States is going to follow suit. Superconductivity is also used in the medical field. These magnets can help identify what’s going on inside a person’s body. The magnetic field attracts the hydrogen molecules found in the human body and accept the energy.
Because there are electrical currents that can flow through superconductors, powerful electric generators use this material instead of copper wiring. The company General Electric has the most optional worldwide market for superconductive generators. Other companies use superconductivity for energy storage to enhance power stability.
