An electromagnet is simply a coil of wire.  It is usually wound around an iron core.  However, it could be wound around an air core, in which case it is called a solenoid.  When connected to a DC voltage or current source, the electromagnet becomes energized, creating a magnetic field just like a permanent magnet.   The magnetic flux density is proportional to the magnitude of the current flowing in the wire of the electromagnet.

This Miniature Linear Actuator Stroke Length 600mm, 5mm/S, 6000N, 12V is an electric push rod and an ideal solution for industrial, agricultural machinery, construction, clean sweeping vehicles, vessels, cargo and many other applications. This electric push rod is a kind of electric driving device which transforms the rotary motion of the motor into the linear reciprocating motion of the pushrod. It can be used in various simple or complex processes as executive machinery to realize remote control, centralized control or automatic control. The electric push rod is composed of the drive motor, reduction gear, screw, nut, guide sleeve, pushrod, sliding seat, shell, micro-motion control switch, etc.
