Comments Off on How Do Electromagnetic Coils Work?What are Electromagnetic Coils?
Comments Off on What are Electromagnetic Coils?Coils are helically wound electrical wires that generate electromagnetic fields when exposed to an electrical current. They are vital parts of various devices, including electromagnets, solenoids, and inductors. A range of applications, from antennas to electric motors, rely on electromagnetic field generation from coils. Coils deliver many benefits and can be made from a diverse […]
Magnetic Levitation
Comments Off on Magnetic LevitationAlso known as magnetic suspension, magnetic levitation (maglev) occurs when magnetic fields suspend an object in the air, with magnetic force overcoming gravitational force to keep it aloft. The idea of magnetic levitation has been around since at least 1904 when Robert Goddard, an American inventor and professor, authored a paper based on magnetic levitation […]
Electrical Coil Design: Thermal Challenges
Comments Off on Electrical Coil Design: Thermal ChallengesElectric coils conduct energy and allow for inductance to counter or control the flow of current. The coils are constructed from wires (made from conductive materials like copper) which may be wound around a cylinder, disk, or toroid-shaped ferromagnetic core or as a self-supported structure (wire only). While electric coils operate based on simple principles, […]
What is High-Density Plasma Technology?
Comments Off on What is High-Density Plasma Technology?High-density plasma domes have traditionally been used as decorative objects due to their unique lighting effects, but they are also an integral part of the semiconductor manufacturing industry. This blog will explain high-density plasma domes and their modern applications in further detail. High-Density Plasma Domes Also called a plasma globe, a plasma dome is a […]
Real World Applications of Electromagnets
Comments Off on Real World Applications of ElectromagnetsAs common as they are, electromagnetic devices are not as widely understood. An electromagnet uses an electrical current to generate a magnetic field. The strength of that field is directly proportional to the level of current supplied to the magnet, and the field’s polarity can be flipped by changing the direction of the electrical current. […]
Inductors vs. Electromagnets: Applications and Capabilities
Comments Off on Inductors vs. Electromagnets: Applications and CapabilitiesInductors and electromagnets are widely used components in electrical devices such as motors, generators, and transformers. While both components utilize a wire coil to establish a magnetic field, they each have functional differences that influence their suitability for a given application. Here, we highlight their similarities and differences while providing examples of how each is […]
Types of Inductors
Comments Off on Types of InductorsAn inductor is one of the basic electrical components commonly used in electric circuits. Typically, an inductor consists of an electrical conductor wound into a coil, often including an iron core. The inductor stores energy in a magnetic field when current flows through it. This magnetic field induces an electromotive force (in the form of […]
What is a Solenoid?
Comments Off on What is a Solenoid?A solenoid is a variety of electromagnet consisting of a copper wire coil wound tightly into a helix, an iron or steel housing, and a mobile plunger made of magnetic material. When an electric current passes through the coil, the solenoid produces a magnetic field and converts that magnetic energy into mechanical motion. Essentially, a […]
