An electromagnetic field
Yes, a solenoid typically uses a movable core, such as a plunger or armature, that moves back and forth inside the coil as a result of magnetic forces. This movement of the core is controlled by the application of current to the coil, which generates a magnetic field that attracts or repels the core.
You would feel resistance as you push the plunger due to the pressure it's creating. Once you overcome the resistance, you may feel a sudden release or movement as the plunger moves through the medium it's interacting with.
A solenoid is an electromagnet with a spring-loaded movable iron slug inside. When current flows through the coil the slug moves. You can connect anything you want to that slug ... electrical switches, speakers, a bell - let your imagination run wild.
When a force moves something parallel to the direction of that force, it is called translational motion. In translational motion, the object moves along a straight path without rotating or changing orientation.
Work is performed when a force moves an object through a distance. Work is calculated by multiplying the force applied by the distance over which the object moves in the direction of the force. The unit for work is the joule (J).

In many ways a solenoid valve is like a regular valve. It opens and closes to let the fluid or gas get through the pipe. The difference is that a solenoid does the work. A solenoid is an electrical device with a coil of wire surrounding a plunger. When electricity flows through the coil, the plunger moves up or down, due to the electromagnetic field.

Yes, atmospheric pressure acts on both sides of the plunger in a sealed syringe. The pressure outside the syringe applies force on the outer surface, while the pressure inside the syringe is influenced by the contents within. If the plunger is pushed or pulled, the pressure difference between the inside and outside can create a force that moves the plunger. However, in a sealed environment, the pressure inside can change based on the volume of the fluid inside the syringe.
A piston is a plunger, or a plug that moves inside a cube, a cylinder. The piston diameter is the diameter of this plunger/plug. It's a tiny bit smaller than the diameter of the cylinder the piston moves in.
You would feel resistance as you push the plunger due to the pressure it's creating. Once you overcome the resistance, you may feel a sudden release or movement as the plunger moves through the medium it's interacting with.
The basic principal is a coil of wire wrapped around a non ferrous cylinder. In this cylinder there is a ferrous metal plunger which can move freely the length of the cylinder. A spring against the plunger holds the plunger so that it is only allowed to enter the cylinder by about a quarter of its length. When current is applied to the solenoid coil the plunger is drawn into the cylinder by the electromagnetic field generated by the coil. On the end of the plunger there is a seal that is used to cover a small hole in the valve body. When this hole is opened the main valve opens. When the current is removed from the coil the plunger is pushed back by the spring to cover the small hole in the valve body and there by closing the main valve.
When an electron moves along the axis of a long straight solenoid carrying a current I, the magnetic field inside the solenoid is uniform and directed along the axis. According to the Lorentz force law, the force acting on a charged particle moving in a magnetic field is given by ( F = q(\mathbf{V} \times \mathbf{B}) ), where ( \mathbf{V} ) is the velocity of the electron and ( \mathbf{B} ) is the magnetic field. Since the velocity of the electron is parallel to the magnetic field in the solenoid, the cross product ( \mathbf{V} \times \mathbf{B} ) equals zero. Thus, the force acting on the electron due to the magnetic field of the solenoid is zero.
The difference between a piston and a plunger may be understood if you observe what forms the seal that precludes the fluid from passing either the Plunger or Piston. The 'piston' is a steel block equipped with elastomers that makes wall contact with the cylinder wall. As it moves inside the cylinder it wipes the wall and displaces the entire content of the cylinder. In this case the seals form part of the piston. The 'plunger' is a steel block that moves through a hole that is equipped with elastomer seals. The plunger displaces a portion of the cylinder contents, i.e., the volume of the plunger that enters the cylinder. The plunger does not wipe the walls of the cylinder. The seals, in case, are a part of the cylinder block. Umair Aslam Mechanical Engineer PARCO, Pakistan
he solenoid of an autmobile is associated with the starter system and transfers an electric current into the starter motor to set the engine into operation. When the ignition key is turned, current is released from the battery and travels along an insulated wire into the solenoid. The solenoid then releases a small plunger that creates a connection between two internal electrical posts, sends the current down another wire to the starter and forces the starter motor to spin.
A solenoid is an electromagnet with a spring-loaded movable iron slug inside. When current flows through the coil the slug moves. You can connect anything you want to that slug ... electrical switches, speakers, a bell - let your imagination run wild.
