Paramagnetism Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field and form internal induced magnetic fields in the direction of the applied magnetic field. Materials or substances that display Paramagnetism are referred to as paramagnetic. Some compounds and most chemical elements are paramagnetic under certain circumstances. … Read more
In the motors or generators, both the parts like rotor and stator play a key role. The main disparity between them is that the stator is an inactive part of the motor whereas the rotor is the rotator part. What Is A Stator?

UPS devices also provide protection from power surges. A UPS contains a battery that ‘’kicks in’’ when the device senses … Read more
Wind occurs because of horizontal and vertical differences (gradients) in atmospheric pressure. Accordingly, the distribution of winds is closely related to that of pressure. Near the Earth’s surface, winds generally flow around regions of relatively low and high pressure –cyclones and anticyclones respectively. Cyclones A cyclone is a large scale air mass that rotates around … Read more
What Is Aldehyde?

North America has a relatively huge landmass (approximately 24, 709, 000 square kilometers) about 16.5% of the earth’s land area and about 4.8% of its total surface. In this regard, Pacific Time (PT) zone is never enough to be the only time reference. As a result, PDT and PST were introduced. PDT and PST are … Read more
Viscosity and density are important concepts when it comes to understanding behavior of liquids and gases. So let us look at the major differences between viscosity and density. Also we will define their roles in the world of science and engineering. What is Viscosity? Viscosity is resistance of a fluid (liquid or gas) to a change in shape, … Read more
