A magnetic relay is an electromechanical device that employs magnetic forces, generated by electrical signals, to control the opening and closing of switch contacts. This function allows it to turn various circuits or devices on or off based on the current flow.
The core components of a magnetic relay include a coil, an armature, and movable contacts. As electrical current passes through the coil, it generates a magnetic field, which in turn attracts the armature. This armature is connected to the movable contacts; its movement, caused by the magnetic attraction, alters the contacts' position, thus switching an electrical circuit either on or off.
Common applications of magnetic relays involve signal amplification in computer circuits and the control of high-power circuits, such as those found in electric motors or generators, providing a reliable means to manage high current flows indirectly.
