Question

Solenoid valves used in washing machines and car engines serve what function?

Options

• They drive speaker cones for sound production

• They create rotating magnetic fields for motor operation

• They control fluid flow in hydraulic and pneumatic systems

• They produce stable magnetic fields for medical imaging

Answer 1

Solenoid valves are used in hydraulic and pneumatic systems to control fluid flow, with examples including washing machines and car engines. When current flows through the solenoid, the resulting magnetic field actuates the valve mechanism, opening or closing the fluid path.
