You wake up in the morning and grab a drink from your refrigerator. Next, you take a shower and drive to your workplace. All this time, you use a set of automatic devices, most of which work due to the existence of a solenoid.
1. What is a solenoid?
A solenoid is a type of electromechanical device that turns electrical energy into mechanical movement. In most cases, it consists of a coil, a housing,, and an armature or piston. An electric current flows through the coil and produces a magnetic field that attracts or repels the armature. Such a device helps activate and deactivate various components of automated systems.
At present, solenoids find application in modern households, automotive systems, household appliances, HVAC systems, gaming devices, and industrial automation.
2. Definition of a Solenoid
As it has been already mentioned above, a solenoid is a device that converts electrical energy into motion using the principle of electromagnetism. Once the coil of the device gets energized, the magnetic field acts on a plunger that pulls it.
In the case of power loss, a spring or magnetic force returns the plunger to its original position.
Owing to their fast response time, reliability, and compactness, solenoids are widely used in:
Intelligent door locks
Fridges
Washing machine
Dryer.
HVAC systems
Irrigation systems
Controllers in games
Circuit breaker
Car starters.
Electromagnetic solenoid is very useful in automation due to their instantaneous switching on and off and low power consumption.
3. Uses of Electromagnet in Today’s Homes

3.1 Solenoid Starters
The solenoid is important for starting cars. Starter solenoid can be regarded as relays that close an electrical circuit between the battery and the starter motor.
Once the key is turned on or the start button pushed, an electric current activates the solenoid. The contacts become closed due to the magnetic field, and the solenoid allows plenty of current flow to reach the starter motor and start the car’s engine.
Without a starter solenoid, a car cannot be started.
3.2 Door Bell Chime
Doorbells represent a very popular example of the use of solenoids.
Once a person pushes the doorbell button, electricity is directed to a solenoid. As a result, a piston hits a tone bar and makes a famous “ding-dong” sound.
The majority of contemporary doorbells still use mechanical solenoid chimes because they are more reliable and make louder sounds.
3.3 Intelligent Door Locks
Modern intelligent locks and security systems rely on latching solenoid.
Once a door is closed, a latching solenoid stops working and consumes minimal energy. Once someone uses a fingerprint recognition or mobile phone, the solenoid receives energy and unlocks the lock.
Latching solenoid consume low energy because they are switched on and off.
3.4 Gaming & Simulation Equipment
Advanced video games and driving simulators use solenoid in order to create a feeling of touch and resistance.
In this way, the majority of simulation devices use latching solenoid to keep controls in place when they aren’t used. Such solenoids are used in order to create a sensation of real resistance when turning the wheel.
Latching solenoid consume lower energy than constantly powered actuators owing to low-energy-consumption DC power.
3.5 Automatic Sprinklers Systems
Sprinkling systems rely on solenoid valves in order to direct water to the appropriate area.
When the sprinkler timer gives a signal to the solenoid valve, the latter is turned on,, and water starts flowing from the sprinklers. ers. Valves are automatically closed once the sprinkling process finishes.
A solenoid is being applied in sprinkling systems in order to save water without damaging your lawn.
3.6 HVAC Equipment
Modern HVAC systems use solenoids in order to switch refrigerants, air flows, and hot water.
Pilot-operated solenoid valves are widely used in HVAC equipment because of their ability to provide high flow rates in small sizes. Valves open and close automatically to keep temperature controlled in different parts of the house.
It is worth noting that modern zoned HVAC systems wouldn’t work without solenoids.
3.7 Refrigerators
Some solenoid is used in modern refrigerators.
3.8 Control of Compressor
Solenoid is responsible for the regulation of the compressor’s pressure and refrigerant flows.
3.9 System of Ice Dispersers
Solenoid is also used in ice-dispensing units. There is a lever on the side of the dispenser that, once pulled, opens a gate allowing cubes of crushed ice to to flow through the dispenser.
These systems guarantee proper operation of modern refrigerators.
3.10 Automatic Ironing Machine
Modern steam ironing systems also use a solenoid to control flows of steam.
Once someone presses the button, the solenoid opens a valve allowing steam to flow through the iron’s nozzle. It helps to control steam properly without overheating.
3.11 Solenoids Dryers
Solenoid valves used in dryers help control evaporator temperature and airflow. They regulate the temperature in hot gas bypass systems, thus increasing energy efficiency and stability.
3.12 Floor Cleaning Appliances
Modern vacuum cleaners use solenoid valves in order to regulate flows of water and detergent to the cleaning device.
Once a user turns on the valve, it delivers cleaning fluid precisely and prevents wasting of water.
3.13 ThermoelectricHeaters
Solenoids are also used in thermoelectric heaters in order to regulate hot and cold water.
One valve regulates a flow of cold water inside the heater, and another one directs the flow of warm water through pipes in order to deliver it to radiators, bathrooms,, and kitchens.
In case of leakage, solenoid valves immediately stop the flow of water.
3.14 Circuit Breakers
Circuit breakers protect your house against electrical overload.
When there is a huge current passing through the system, a magnetic field generated inside the solenoid breaks the circuit.
Unlike ordinary fuses, solenoids can be restored once an electric current is reduced and the circuit becomes safe.
4. Advantages of Using Solenoids

Modern solenoids have several important advantages.
Fast response time
Compact structure
