The basic principle and application of proportional electromagnet!

A proportional electromagnet is a device that generates force using the principle of electromagnetic induction, based on the property of creating a magnetic field when an electric current passes through a wire. The following is a detailed introduction to the basic principles and applications of proportional electromagnets.
Basic principle
A proportional electromagnet consists of an iron core and a coil wound around the core. When an electric current passes through the coil, the resulting magnetic field makes the iron core magnetic, creating an electromagnet. Its working principle can be described by the right hand spiral rule: when the right hand holds the wire, the thumb points to the direction of the current, and the other four fingers point to the direction of the magnetic field, the magnetic direction of the iron core can be learned.
Application field
Electromagnetic sucker: Proportional electromagnets are often used in electromagnetic sucker systems. By adjusting the strength of the current, the adsorption force of the sucker can be precisely controlled, and various materials can be suspended and fixed. Maglev technology: Proportional electromagnets also play a key role in maglev trains and maglev display devices. By adjusting the current, the strength of the magnetic field can be controlled to achieve the suspension and movement of the train or suspended object.
Solenoid valve control: In industrial automation, proportional electromagnets are widely used in the control of solenoid valves. By adjusting the current, the valve can be accurately controlled to adjust the flow and pressure of the fluid.
Electromagnetic sensors: Proportional electromagnets can also be used to make electromagnetic sensors for detecting and measuring the strength of magnetic fields. This has important applications in fields such as magnetic field measurement and navigation.
