Hard Magnetic Materials

For understanding the hard magnetic materials , we have to know certain terms. They are as follows: Coercivity: The capability of a ferromagnetic material to hold up (resist) a peripheral magnetic field without getting demagnetized. Retentivity (Br): It is the amount of magnetism that a ferromagneti

Ferroelectric Materials: What Are They?

What are Ferroelectric Materials? Ferroelectric materials are materials that exhibit Ferroelectricity. Ferroelectricity is the ability of the material to have a spontaneous electric polarization. This polarization can be reversed by the application of an external electric field in the opposite direc

Soft Magnetic Materials

First of all we need to keep certain points in mind before defining the soft magnetic materials . Remanent Induction: It is actually the value of induction which residue, once the material is magnetized and then the magnetizing field is decreased to zero. It is denoted by B r . Coercive Force: It is

What is Superconductivity?

Superconductivity was discovered by Dutch Physicist Heike Kamerlingh Onnes in 1911 in Leiden. He was awarded the Nobel Prize in Physics in 1913 for his low-temperature research. Some materials when they are cooled, below certain temperature their resistivity get abolished means they exhibit the infi

Meissner Effect and Application of Meissner Effect

When Superconductors , are cooled below the critical temperature, they expel magnetic field and do not allow the magnetic field to penetrate inside them. This phenomenon in superconductors is called Meissner effect . This phenomenon was discovered by German physicists “Walther Meissner” and “Robert
