There are two types of superconductor materials Type-1 superconductor Type-2 superconductor Type-1 superconductor They are also called as Soft Superconductor. Their critical field and transition temperature are low. They exhibit complete Meissner’s and Silsbee rule. The change of state from normal to superconductivity and vice-versa is abrupt. Examples: Zn, Pb, Hg, Al, In, etc. Type-2 superconductor They are also called as Hard Superconductor … Read more
Before selecting an insulation system for a particular application, the following properties need to be considered. Mechanical Thermal Environmental including chemical Electric Economic 1. Mechanical properties The mechanical properties considered are the tensile strength, elongation, tensile modulus, compressive modulus, impact strength etc. 2. Thermal properties Include temperature and time of exposure. In this, the important … Read more
In previous, article we discussed ECG (Electrocardiogram). In this article, we will see about different types of ECG. The type of ECG monitoring depends on the frequency and severity of symptoms. There are three types of ECG monitoring i.e. resting ECG, stress ECG, and ambulatory ECG. Ambulatory ECG is divided into 3 groups i.e. Holter monitors, … Read more
In single crystal material such as iron, the magnetic properties of a material depend on the direction in which they are measured. This property of the magnetic material is called as Magnetic Anisotropy. There are three methods to induce Magnetic Anisotropy Cold Working Magnetic Annealing Magnetic Quenching 1. Cold Working such as cold rolling induced the uniaxial magnetic … Read more
The magnetic materials are classified into 5 types Diamagnetic Material Paramagnetic Material Ferromagnetic Material Anti-ferromagnetic Material Ferri Magnetic Material 1. Diamagnetic Material These material have smaller and negative magnetic susceptibility. These material are repelled by applied magnetic field. The magnetic flux density inside diamagnetic material is zero. B = 0 µo[ H + M ] = … Read more
Holter Monitor It is a small, wearable device that records your heart rhythm. It is very similar to a mobile phone. A patient usually wears a Holter monitor for one to three days. The device will record all of your heart rhythms during that time. So, a Holter monitor test is usually performed after an ECG (electrocardiogram) … Read more
Magnetostriction When a material (magnetic material) is magnetised, changes in dimension are generally observed. This property of a magnetic material is called magnetostriction. There are three types of Magnetostriction Longitudinal Transverse Volume 1. Longitudinal Magnetostriction When a change in the dimension is in the direction of applied field. 2. Transverse Magnetostriction When a change in the dimension is perpendicular … Read more
Chemical Bonding The binding forces between atoms or molecules are known as a chemical bond. There are two types of chemical bond. Primary Secondary Primary Bond These are the interatomic bond. These bond are having higher bond energy. Examples: Ionic, covalent and Metallic bond. Secondary Bond These are the intermolecular bond. These bond are having … Read more
Conductors are mainly made up of Copper, Aluminium and their alloys. Stranded Conductors Greater flexibility and mechanical strength than the single wire of same crossectional area. Total number of conductor is a strand of n layer = 1 + 3n(n + 1) Overall diameter of stranded conductor = (2n + 1)d where, d = diameter … Read more
