A solenoid is a simple electromagnetic device that converts electrical energy directly into linear mechanical motion, but it has a very short stroke (length of movement), which limits its applications.
Stop solenoid and ignition key working can be learned by watching this video, how does a vehicle starts when you turn the key and how the fuel gets into the. A rotary solenoid is a unique type of solenoid which is used for various applications where there is a need for easy automatic control process. It works on the same principle as the other solenoids and has the same elements, a coil and a core, but they have a different operation. Solenoid working Make a basic solenoid. For the core body of the solenoid, we can just use part of a plastic Bic pen. I have melted the ends and flattened them to help contain the copper coil. For the piston I’ll use an iron nail and to ensure it fits into the centre of the pen I’ll just use a needle file to ensure a smooth fit.
Basic working principle of solenoid:
The solenoid consists of a coil of wire with an iron plunger that is allowed to move through the center of the coil. Above figure shows the solenoid in the unenergized state.

Notice that the plunger is being held about halfway out of the coil by a spring. When the coil is energized , the resulting magnetic field pulls the plunger to the middle of the coil. The magnetic force is unidirectional — a spring is required to return the plunger to its un energized position.

A solenoid valve is the combination of a basic solenoid and mechanical valve. So a solenoid valve has two parts namely- Electrical solenoid, mechanical valve.
Solenoid converts electrical energy to mechanical energy and this energy is used to operate a mechanical valve that is to open, close or to adjust in a position.

Limitation of Solenoid valve
The main limitation of the solenoid is its short stroke, which is usually under an inch.
Still, there are many applications for short-stroke linear motion; examples are activating electric car-door locks, opening and closing valves, and triggering mechanical latches.
Most applications use the solenoid as a on or off device — that is, the coil is either completely energized or switched off. However, variable-position control is possible by varying the input voltage.
