Pronunciation: [sˈə͡ʊlənˌɔ͡ɪd] (IPA) 
The word "solenoid" is spelled with an "o" followed by an "e" and pronounced /ˈsoʊlənɔɪd/. The "o" in the first syllable is pronounced like "oh" as in "so", and the "e" in the second syllable is pronounced like "oy" as in "boy". A solenoid is typically a coil of wire that generates a magnetic field when an electric current flows through it. This word is commonly used in the fields of electrical engineering and physics.
A solenoid is an electrical device that consists of a tightly wound coil of wire wrapped around a metal core. It functions as an electromagnet when an electric current passes through it. The key characteristic of a solenoid is its ability to generate a magnetic field when energized. This magnetic field can then produce a mechanical force, which is utilized in various applications.
The core of a solenoid is typically made of a ferromagnetic material, such as iron or steel, which increases the strength and concentration of the magnetic field. The coil of wire is wound uniformly around the core, ensuring that the magnetic field is evenly distributed. When an electric current flows through the wire, a magnetic flux is generated, causing the solenoid to attract or repel nearby magnetic materials.
Solenoids are extensively used in numerous devices and systems for their ability to convert electrical energy into mechanical energy. They find applications in electromagnetic valves, actuators, relays, switches, and locks, among others. Solenoids are particularly useful due to their simplicity, compact size, and high efficiency.
In summary, a solenoid is an electromechanical device that transforms electrical energy into mechanical motion by generating a magnetic field. Its practical applications are diverse, ranging from controlling fluid or gas flow to actuating mechanical devices in various fields such as automotive, industrial, and household appliances.

The word "solenoid" derives from the Latin term "solēn", meaning "pipe" or "channel". In the 19th century, French mathematician André-Marie Ampère utilized this term to describe a helical coil of wire that resembled a pipe. The subsequent English modification of the word to "solenoid" retained its core meaning while also emphasizing its cylindrical and tubular shape. Today, "solenoid" refers to a coil of wire that creates a magnetic field when an electric current passes through it, commonly used in various electrical devices.
