Solenoids

Solenoid -  on a rod-shaped form made of solid iron, solid steel, or powdered iron, a solenoid is a coil of insulated or enameled wire-wound. This kind of devices can be used as,  inductors in electronic circuits,  miniature wireless receiving antennas and electromagnets.

In a solenoid, the core material is ferromagnetic, which concentrates magnetic lines of flux. With an air-core coil of the same dimensions and the same number of turns, this increases the inductance of the coil, far beyond the inductance obtainable . Near the ends of the core; Some flux appears outside the coil,  outside the coil a small amount of flux also appears and off to the side.

With a movable, solid iron or steel core, a solenoid chime is wound on a cylindrical, hollow, plastic, or phenolic form. Along its axis, The core can travel in and out of the coil. The core normally rests somewhat below the coil center, and it is oriented vertically. The magnetic field pulls the core forcefully upward, when a current pulse is applied to the coil. above the center of the coil, Inertia carries the core where the core strikes a piece of metal , causing a loud "ding", similar to a xylophone bell.

How Do Electromagnet Solenoids Work?

It produces a magnetic field, once that charge gets some motivation and goes for a run around the block, suddenly. Both fields are part of the same force of nature: electromagnetism, as physicists figured out later.

We can create a magnet by simply running a current through a wire, because of this.because the magnetic field is concentrated inside the coil,   a solenoid, we run a current, however, we get a super-strong magnet.  In our everyday lives, this can be extremely useful.

Uses of Electromagnet Solenoids

All over the world, electromagnetic solenoids find use.  Water-pressure valves in air conditioning systems, are in hotel door locks, MRI machines, hard disk drives, speakers, microphones, power plants, and cars. Without hitting a solenoid, you can hardly swing a bat.

Speakers and microphones, for example, both contain solenoids. Speaker and microphone in reverse of each other are the same thing. Through a solenoid to create motion, a speaker takes electrical signals and runs them; that motion drives the speaker and creates a sound. Your voice pushes the solenoid back and forth, a microphone does the opposite, and that motion of the solenoid creates an electrical signal that can be used to create the sound elsewhere.  We can not  record or reproduce sound at all, without solenoids.
