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 Levitation

Also 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 Challenges

Electric 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, […]

Real World Applications of Electromagnets

Comments Off on Real World Applications of Electromagnets

As 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 Capabilities

Inductors 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 Inductors

An 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 […]
