Do you know solenoid valve? How’s it made? Now let me introduce for you.

Structure: A solenoid typically consists of a coil of wire wound around a movable metal core (plunger).
Working Principle:
When electric current passes through the coil, it creates a magnetic field. This magnetic field pulls or pushes the plunger inside the coil, creating motion.
Types of Motion:
• Pull-type solenoid: The plunger is pulled into the coil when energized.
• Push-type solenoid: The plunger is pushed out when energized.
Applications:
• Solenoid valves: Control the flow of gases or liquids.
• Relays and contactors: Switch electrical circuits.
• Locking systems: Electric door locks or latching mechanisms.
• Automotive systems: Fuel injectors, starters, transmission controls.
