Cách sử dụng
A solenoid is a type of electromagnet that is used in many everyday devices. It's a coil of wire that creates a magnetic field when an electric current runs through it. People use solenoids in things like car engines, door locks, and washing machines. For example, when you press a button to lock your car, a solenoid in the door receives an electrical signal, which causes a small metal rod to move and lock the door. In short, solenoids play a crucial role in the functioning of many modern devices.
