Applications of a Solenoid
The applications of solenoid are mentioned below:
- Door locking mechanisms: Mechanical model in which circuit of solenoid is completed when correct combination of keys are aligned.
- MRI machines: Function of solenoid in MRI machines is to generate magnetic field required for imaging process.
- Mechanical or fluid control valves: With help of its magnetic property, solenoids are used to control opening and closing of mechanical and fluid valves.
- Motors and Generators: Solenoid act like initiating-mechanism for motors and generators. They are used to create magnetic fields in solenoid.
Solenoid
A solenoid is an electromagnetic device made out of a coil of wire wound around a cylindrical or elongated core, usually comprised of ferromagnetic material like iron or steel. When an electric current flows through a wire coil, it generates a magnetic field surrounding it, which can exert force on objects in the field or cause mechanical motion. In this article, we will learn in detail about solenoid, its working and application.
