Superconducting materials can be used for: power transmission and storage, medical devices, magnet manufacturing, and more.
1. Electricity transmission and storage
Superconductors can be used to build superconducting cables, which can transmit electricity more efficiently. Superconducting cables can reduce losses and therefore reduce energy waste. In addition, superconductors can be used to build superconducting batteries, a new type of battery technology that can store large amounts of energy and have a long lifespan.
2, medical equipment
Superconductors also have a wide range of applications in medical equipment. For example, superconducting magnets can be used in nuclear magnetic **** vibration imaging (MRI) machines to generate extremely strong magnetic fields. Superconducting magnets can also be used to make artificial hearts to help people who need heart transplants or assistive devices.
3, magnet manufacturing
Superconductors can also be used to make superconducting magnets. Superconducting magnets can generate extremely strong magnetic fields, so they can be used in many applications, such as nuclear fusion experiments, particle gas pedals, and magnetic levitation trains.
Introduction of the technical principles of superconducting materials:
1. Zero resistance
Superconducting materials in the superconducting state have zero resistance and are able to transmit electrical energy without loss. If a magnetic field is used to induce an induced current in a superconducting ring, this current can be maintained without degradation. This "continuous current" has been observed in experiments many times.
2, anti-magnetic
Superconducting materials in the superconducting state, as long as the applied magnetic field does not exceed a certain value, the magnetic lines of force can not penetrate the superconducting material within the magnetic field is always zero.
3, critical temperature
The temperature at which a superconducting material changes from its normal state to a superconducting state (or vice versa) when the external magnetic field is zero is expressed as Tc. The value of Tc varies with different materials. The lowest Tc that has been measured for a superconducting material is for tungsten, at 0.012 K. By 1987, the maximum critical temperature had been raised to about 100 K. The temperature of a superconducting material can be measured at about 0.012 K.
