Infrared (IR) is a type of electromagnetic radiation that has a longer wavelength than visible light but shorter than radio waves. The wavelength of infrared radiation ranges from approximately 700 nanometers (nm) to 1 millimeter (mm). IR radiation is emitted by all objects with a temperature above absolute zero, and its intensity and wavelength distribution…
Radio waves are a type of electromagnetic radiation that have wavelengths longer than those of visible light, ranging from about 1 millimeter to 100 kilometers. They are produced by various natural and man-made sources, such as the sun, lightning, and electronic devices. Radio waves can be used for a variety of purposes, including communication, navigation,…
Electromagnetic waves are a type of wave that consists of oscillating electric and magnetic fields that propagate through space. These waves are characterized by several properties, including: What is Electromagnetic waves and their characteristics Electromagnetic waves are a type of wave that consists of oscillating electric and magnetic fields that propagate through space. These waves…
Electromagnetic induction is the process of generating an electric current or electromotive force (EMF) by a changing magnetic field. It was discovered by Michael Faraday in the 1830s and is one of the most important principles of electromagnetism. Faraday’s law of electromagnetic induction states that when a magnetic field changes with time, it induces an…
Conversions typically refer to the process of turning a prospect or potential customer into an actual paying customer. In digital marketing, conversions can refer to a specific action that a user takes on a website, such as filling out a form, making a purchase, or subscribing to a newsletter. The conversion rate is the percentage…
A voltmeter is an instrument used to measure the voltage difference between two points in an electric circuit. It is typically connected in parallel with the component or circuit being measured, and it provides a reading of the voltage across that component or circuit. Voltmeters can be analog or digital and can be designed to…
When a current-carrying wire is placed in a uniform magnetic field, a magnetic force is exerted on the wire. This force is perpendicular to both the direction of the current in the wire and the direction of the magnetic field. The magnitude of the force is given by the equation F = BIL, where F…
A moving charge in an electric field experiences a force that is proportional to the strength of the electric field and the magnitude of the charge. The direction of the force is given by the direction of the electric field and the sign of the charge. The mathematical expression for the force on a moving…
When an electric current flows through a straight wire, it creates a magnetic field around the wire. This magnetic field is known as the “magnetic field near a current-carrying straight wire.” The magnetic field is perpendicular to the wire and its direction is given by the right-hand rule. If you point your right thumb in…
Biot-Savart’s law is a fundamental law in electromagnetism that describes the magnetic field produced by a steady current in a wire. It states that the magnetic field at a point in space due to a current-carrying wire is directly proportional to the current in the wire and the length of the wire segment, and inversely…
