Solenoids are a well known application where magnetic fields are used to create controlled magnetic force. Solenoids are used in various industries where they [[wysiwyg_imageupload::]]serve the purpose of hydraulic valves, current limiting switch, steering control of heavy machines etc.   This version of Insight details with DC operated tubular solenoid which is often used as an actuator. Comprising of a metallic can, coil, soft iron cored plunger along with insulator coating and connecting wires, linear solenoids are almost noiseless. Depending upon the movement of the plunger, these solenoids can be divided into push type (where plunger goes inside the metallic can) and pull type (plunger comes out of the tin can). Tubular solenoids can work for longer hours without getting their coil overheated or burnt out.  Let’s find out what more constructional and operational features of one such tubular solenoid in this Insight.
