A solenoid valve opens when what occurs?

Explanation:
Solenoid valves open when an electrical current flows through the coil, creating a magnetic field that pulls the internal plunger and allows flow. The key idea is that the magnetic field is produced by the current; without the current, there’s no electromagnet action to move the valve. Temperature differences or manual turning don’t energize the coil, so they don’t cause the valve to open. Some solenoid valves are normally closed and open when energized, but the essential trigger is the electrical current generating the magnetic field.
