Introduction Light is represented by an Electromagnetic Wave (EMW), where it travels by oscillating electric and magnetic field intensities simultaneously. Here, the electric field will be perpendicular to the magnetic field and vice versa. Not only that, these two components together oscillate perpendicular to the direction of propagation of light waves. Mainly, oscillations due to electric fields in a plane are considered for the light as electromagnetic waves when compared to magnetic fields. Hence, light electromagnetic waves are also called transverse waves. Since the atoms that produce EMW can vibrate or oscillate in all directions, it will be difficult to ... Read More

Introduction The damping in very simple words is an opposing influence on the motion of any object. Electromagnetic damping is deeply related to the concept of electromagnetic induction, hence it is very important to learn about the induction of electro-motive force (emf) in the first place. Through this tutorial, we shall discuss why the induced currents ( eddy currents) are formed and how they influence the motion of the object or the conductor. The relation and proportionality of electromagnetic damping with various factors like the strength of the magnetic field, the velocity of the object, induced current value, etc is ... Read More

Introduction We see beautiful nature through light, which is an electromagnetic wave. We hear sweet melodies through sound waves. Waves have numerous applications in everyday life, from cellular communication to laser surgery. If we drop a stone on a steady surface of the water, we will see a reflection on the surface of the water where the stone hits it. In today's modern technological world, the influence of mobile phones in our daily life is very high. It is an efficient means of sending messages from one point to another quickly and efficiently. Electromagnetic Waves Electromagnetic waves are waves that ... Read More

Introduction Light travels across space and different media in the form of electromagnetic waves. The term electromagnetic means they contain both electric as well as magnetic fields. Akin to other waves, light waves are also characterized by a certain frequency and wavelength. For example, light waves with frequencies in the range of 400 to 800 THz fall in the visible region and we can see them with the naked eye. Red color has the highest wavelength at around 600 nm and thus, the lowest frequency, whereas violet light has the highest frequency in the visible region. In this tutorial, we ... Read More

Introduction The electromagnetic spectrum encompasses a wide range of radiation emitted by stars, such as our sun. Waves of electromagnetic radiation commute through space. The frequency of a wavelength explains the no of waves/second it generates. Wavelength is the size of a wave in meters. At one end of the spectrum, radio waves with the lengthiest wavelengths and least frequency exist. One radio wave can travel the length of a football field. Among all electromagnetic waves, radio waves have the greatest size and lowest energy, whereas visible light is measured in inches. In this article we will learn about the ... Read More

Electromagnetic Spectrum Microwave

Introduction Before diving into microwaves, we must study a few basic concepts about the electromagnetic spectrum. As you might be aware, light behaves like a wave in certain situations. Not only that, but it is also an electromagnetic wave, which means it carries both electric as well as magnetic components. Naturally, if the light is a wave, then it must have properties that define its wave-like behavior. For instance, all light waves must be defined by frequency and wavelength. And as it turns out, they are. This gives rise to what is known as the electromagnetic spectrum. The spectrum of ... Read More

Introduction If you haven’t heard about the mystery of the nature of light, here is a quick refresher: Light behaves both as a particle and as a wave in different scenarios. While the causes behind this duality are as of yet, unknown, scientists still have been able to explain these natures independently. Thus, we now know that in terms of its wave nature, light is an electromagnetic wave composed of both electric and magnetic fields, which oscillate in mutually perpendicular directions. And since light behaves like a wave, you can easily understand how it must have a certain frequency and ... Read More

Electromagnetic Radiation

Introduction The concept of electromagnetic radiation came to know when Maxwell derived the four equations to correlate the electric field and magnetic field. With the help of these equations, he found that electric field and magnetic field depend on time and space propagate in the form of traverse waves. According to faraday law, when there is a change in magnetic flux it results in the induction of emf in the circuit. This implies that if magnetic flux causes the emf then surely there is an electric field. Based on this concept, Maxwell found that a time-varying magnetic field is a ... Read More

Introduction Solenoid Engine generally generates a uniform magnetic field when the current passes through the coil that is wrapped around it. In the present day, it has been seen that automobiles, as a primary source chemical energy are used in order to produce combustion heat. This combustion is contributing to general pollutants. Here the Solenoid Engine steps into. It offers more capacity and power without providing pollutants to the environment. Based on this, the tutorial will explain Solenoid Engine, its properties and the applications as well. Definition of Solenoid Engine In order to define Solenoid Engine in a simpler ... Read More

Solenoid Toroid

Updated on 13-Oct-2022 11:19:47
Introduction Solenoid and Toroid are two different concepts of electromagnetism. Toroid is called a solenoid belt into a circular motion and the shape of it is a loop-like structure it is also called a hollow circular ring and a disk-like structure can be seen. On the other hand, solenoid is called a type of electromagnet that is created by the use of a helical wire. What is a solenoid? Solenoid is considered as a long wire wrapped around in a helical shape. Its shape of it is cylindrical and it is used in the research field and experiment. ... Read More
