Superconductivity

Faraday's law of induction
the induced electromotive  force is directly proportional to rate of changes of magnetic flux .

Albert Einstein theory of magnetic and geometrical gravitational waves all the physical law are  the same for the non accelerating observer and the speed of the light is same for the speed of the emitting body.  it is not depend on the speed of the observer ..

Superconducting magnet level 18 above the high temperature superconductors cold with liquid nitrogen persistent electric current flows on the surface of the superconducting to exclude the magnetic field of a magnet Faraday's law of induction this current efficiency of an Electromagnet and that sleeping then I'll let play medium video of this knowledge take effect on the high temperature in magnet levitating about the high temperature semiconductor old with liquid nitrogen persistent electric current flows on the surface of the super conductor waiting on including the magnetic field or magnetic and effective form of coming from the space law of induction electromagnets all the magnetic and video of the height super conductor and black Planet with idioms on magnetic hi temperature superconducting magnet high temperature superconducting magnets pillow a characteristic critical temperature it was discovered by foreign scientist superconductivity is a phenomenon that is exactly 0 electrical resistance and the expansion of a magnetic field during   electric  flow.

The induced electromotive force is directory spontaneously proportional to rate of change of magnetic flux through that curve.
