Explanation

superconducting materials refers to the materials whose resistance is equal to zero and has the characteristics of repelling magnetic lines of force under appropriate low temperature conditions. Its main characteristics include: zero resistance: when the superconducting materials is in the superconducting state, its resistance is zero, and it can transmit electric energy without loss. If an external magnetic field is introduced into the superconducting ring, a current will be induced, and this current can continue unabated. This continuous current has been observed multiple times in experiments. Diamagnetism: when the superconducting materials is in the superconducting state state, as long as the external magnetic field does not exceed a certain value, the magnetic line of force cannot penetrate into the inside of the materials, and the magnetic field in the superconducting materials will remain zero. Isotope effect: the critical temperature (Tc) of superconductors is related to the quality of their isotopes. The higher the mass, the lower the Tc, which is called the isotope effect.
