Magnetic sucker is a device that uses magnetic force to adsorb objects, which is widely used in many fields such as industrial production, logistics and transportation.
Core Parts:
1. Electromagnetic coil
Function: Electromagnetic coil is the key component of electromagnetic jack to generate magnetic field. When the current passes through the coil, according to the law of electromagnetic induction, a magnetic field is generated around it. This magnetic field is the basis for the electromagnetic jack to adsorb ferromagnetic objects. The strength of the magnetic field generated by the coil is directly related to the current size and the number of turns of the coil. By increasing the current or the number of turns of the coil, the magnetic field strength can be increased, thus increasing the lifting force of the jack. For example, when lifting heavy steel components, a strong enough magnetic field is needed to ensure that the components can be stably adsorbated, which requires the electromagnetic coil to provide a large enough magnetic force.
Material characteristics: Electromagnetic coils are generally wound by well-insulated copper wires. Copper has good electrical conductivity, which can effectively reduce the loss of electric energy in the transmission process. At the same time, in order to prevent the coil from being damaged by the heat generated by the current during the working process, the insulation layer of the wire needs to have high temperature resistance. Commonly used insulation materials such as polyester enamelled wire, which can maintain good insulation performance at a higher temperature to ensure the normal operation of the coil.
Car Lifting Magnet Function: The iron core is located inside the electromagnetic coil, and its main role is to enhance the magnetic field. Iron cores are generally made of materials with high permeability, such as electrical pure iron. When the magnetic field is generated by the electromagnetic coil, the core is magnetized, and the magnetic domains inside it are aligned along the direction of the magnetic field, thus enhancing the magnetic field. This enhancement allows the electromagnetic jack to generate a strong enough magnetic field at a small current, improving energy efficiency. Moreover, the shape and size of the iron core also affect the distribution of the magnetic field.
Industrial Lifting Electromagnets Material characteristics: The material used for the iron core needs to have the characteristics of high permeability and low coercivity. High permeability can make the core more easily magnetized, thus better enhancing the magnetic field; Low coercivity ensures that after the current disappears, the core can be rapidly demagnetized to avoid residual magnetism affecting the next use. Electrical pure iron is a commonly used iron core material, it after appropriate heat treatment, the permeability can reach a higher value, and the coercivity is low, can meet the requirements of electromagnetic jack on the core.

Function: The control panel is a key part of the operation of the electromagnetic jack, which can control the adsorption and release function of the electromagnetic jack. Through the control panel, the current size of the input electromagnetic coil can be adjusted to control the magnetic field strength to adapt to different weights and shapes of the adsorbed objects.
Electromagnet For Lifting Steel Component composition: The control panel usually includes a power switch, current regulator, indicator light and other components. The power switch is used to control the power supply of the electromagnetic jack, and is the basic control component of the operation. The current regulator can be either a knob or a button, and is used to precisely adjust the current input to the electromagnetic coil. The indicator is used to show the working state of the electromagnetic jack, such as power on, power off, overload and so on. With these components working together, the operator can easily and safely operate the electromagnetic jack. Crane Magnet
