What is Levitation & Meissner Effect in Superconductivity

cooper pair in Meissner effect and BCS theory

The phenomena of levitation of a magnet above a cooled superconductor is known as the Meissner Effect. If a superconductor is cooled below its critical temperature while in a magnetic field, the magnetic field surrounds but does not penetrate the superconductor. The magnet induces current in the superconductor which creates a counter-magnetic force that causes the… Read More: What is Levitation & Meissner Effect in Superconductivity »

Dielectric Constant of Different Materials or Relative Permittivity

Dielectric Materials A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization. Because of dielectric… Read More: Dielectric Constant of Different Materials or Relative Permittivity »

Capacitor and Capacitance Simplified & Explained

What is a Capacitor? Capacitor is a device that stores electric charge. A capacitor consists of two conductors separated by an insulator. Capacitors have many applications some of them include Computer RAM memory and keyboards, Electronic flashes for cameras, Electric power surge protectors and Radios and electronic circuits. Another definition of capacitor can be that… Read More: Capacitor and Capacitance Simplified & Explained »
