The solenoids are simple electrical components and it has a vast impacts on daily life. The term itself is derived from the Greek name “solen”, which illustrates a channel or a pipe. The second part of the name is taken from the Greek name “eidos”, which refers to an outline. Basically, it is a component in the form of a pipe. The solenoid is used in a variety of applications, and there are numerous types of solenoid designs available. Each of them has their own properties that make it useful in many precise applications. The various designs of these components do not change their necessary operating feature and the designing of the solenoids can be done in different ways. Generally, solenoid works on general electrical principle, but the mechanical energy of this device is distributed in a different way in different designs.
Using Electromagnetism
A solenoid is a coil of wire that produces a magnetic field when carrying an electric current.
The strength of the magnetic field increases as more loops per meter are used and increasing the electric current.
A solenoid is a very simple component, that includes a coil of wire that is covered around a core made out of a metal. When a current is applied to the solenoid, it has the effect of assembling a consistent magnetic field. Electricity changes to magnetism then it changes to electricity and, therefore, these two forces are united into one.
An attractive thing about the uniform field in a solenoid is that, if the solenoid has an immeasurable length, the magnetic field would be the similar everywhere along the element. In a solenoid, sometimes this translates to very small electrical components being able to do a marvelous amount of work. For instance, a powerful solenoid can simply slam shut a valve that would be demanding for even the burliest plumber to close by hand.
Существуют различные типы соленоидов, доступных на рынке. Они отличаются с точки зрения их материала, дизайна и функции. Но все виды соленоидов зависят от одних и тех же электрических принципов.
AC Laminated Solenoid

Linear Solenoid
Rotary Solenoid
Solenoid - a single wire wrapped around a cylinder
In a car or truck, the starter solenoid is part of an automobile starting system. The starter solenoid receives a large electric current from the car battery and a small electric current from the ignition switch.
When the ignition switch is turned on, the small electric current forces the starter solenoid to close a pair of heavy contacts, thus relaying the large electric current to the starter motor.
A solenoid is an essential coil of wire that is used in electromagnets, inductors, antennas, valves, etc. The application of a solenoid differs in numerous types like medical, locking systems, industrial use, the bottom line and Automotive Solenoid Applications.
A solenoid is used to control a valve electrically, for example, the solenoid core is used to apply mechanical force to the valve.
These can also used in particular types of door locking systems, which use an electromagnet and offer a very secure closure.
The solenoid is used in many different appliances and products like computer printers, fuel injection gear used on cars and in various industrial settings.
The main advantage of the solenoid is, whenever an electricity is applied, the reaction of the solenoid is immediate.
Applications of Solenoid
Electromagnets
An electromagnet is made up of a solenoid wrapped around an iron core.
Electromagnets are very useful because they can be turned on and off as needed. The solenoid has a field only when there is electric current in it.
ELECTROMAGNETISMElectromagnet Strength
The magnetic field surrounding a current-carrying conductor can be strengthened (increased) three ways.
Place a soft iron core in the center of the coil.
Increase the number of turns of wire in the coil.
Increase the current flow through the coil windings.
Electromagnetic Induction
The process by which an electric current is made is by changing a magnetic field is called electromagnetic induction.
An electric generator: uses electromagnetic induction to change mechanical energy into electrical energy.
