Solenoid

The core material in a solenoid is of a ferromagnetic nature. As a result, a magnetic field in an activated solenoid has negative and positive poles, and can attract or repel materials which are sensitive to magnets. The electromagnetic field in a solenoid results in the armature moving forward or backward due to the solenoid coil. Solenoids are either used to generate a controlled magnetic field or act as a transducer device capable of producing linear motion. Solenoids are extremely helpful for numerous applications, including automated equipment.
