Thermoplastic sealing type home electrical use solenoid coil diameter 10 height 31

       Electromagnetic coil is used to convert electrical and magnetic energy components, it is composed of a metal wound wire, in most cases form a cylindrical shape, but also other shapes. When the current passes through the coil, a magnetic field is formed in the coil, and the coil can convert electrical and magnetic energy.
      Electromagnetic coils are designed according to the law of electromagnetic force. The law of electromagnetic force states that when a circuit is operated with a current closed, a magnetic field is formed around it. The shape of the circuit can be a closed single coil; It can also be a complex circuit consisting of multiple lines, in which case a total magnetic field is formed by superimposing multiple magnetic fields.
Due to the law of electromagnetic force, if the current is conducted around the electromagnetic coil, it will cause the magnetic field to surge, which is the reason why the coil produces magnetic force, and it is also the principle of coil work.

       The electromagnetic force can also cause the coil itself to vibrate, and it is important to note that the coil itself does not consume energy when it vibrates. When near a magnetic field center, the coil will be pushed, when leaving the magnetic field center, the coil will be pulled, repeated, will be shaken by the coil itself, thus generating energy.
Electromagnetic coils can convert electrical energy and magnetic energy, and the essence of this conversion process is to convert each other, that is, electromagnetic coupling. When the current flowing through the wire creates a magnetic flux in the coil, a magnetic force is generated in the coil, pushing the coil to rotate. When the coil passes through the magnetic field, the coil will be pushed by the magnetic force, so the coil will rotate according to a certain period. In this process, it can be converted from electrical energy to magnetic energy, and from magnetic energy It converts to electricity.

      In general, when the electromagnetic coil is running, it will be driven by the magnetic force, when the current flowing through the wire generates a magnetic flux in the coil, the magnetic force will form a magnetic field outside, so that the coil will be driven by the magnetic force, generate power, and achieve the mutual conversion of electrical energy and magnetic energy
