    • There is a coil inside the electromagnetic pump, and when the current passes through the coil, a magnetic field is generated. The strength of the magnetic field depends on the current.
      Magnetic field action:
      The magnetic field generated by the current in the coil exerts a magnetic force on the iron core inside the pump. This magnetic force attracts or pushes away the core, causing it to move.
      Piston movement:
      There is a piston inside the electromagnetic pump, which is connected with the iron core. When the iron core is attracted by the magnetic force, the piston moves towards the iron core and makes contact with the liquid in the pump.
      Liquid inhalation:
      When the piston moves toward the core, a negative pressure area is created inside the pump, and the liquid is drawn into this area. In this way, the suction of the liquid is achieved.
      Liquid discharge:
      When the piston is separated from the core by a certain distance, the current in the electromagnetic coil is reduced, and the magnetic force is also reduced. At this time, the liquid will be pushed by pressure into the part where the piston is located, thus achieving the discharge of the liquid.
      Cycle process:
      Through this circulation process, the electromagnetic pump is able to draw liquid from one place and expel it through the movement of the pump body to another place. The whole process is driven by the mechanical movement generated by the electromagnetic pump force.
