Electromagnetic lifting

When the wire is wound into a solenoid shape and an iron core is inserted inside, once powered on, the device will exhibit significant magnetism and become an electromagnet. When current flows, the electromagnet has magnetic force; And once the current is interrupted, the magnetism also disappears. One of the main components of an electromagnetic crane is the electromagnet. In construction sites, docks, as well as some workshops and freight yards, there are no shortage of electromagnetic cranes. Operation instructions: Press the "down" button to lower the electromagnet; Press the 'attract' button, power on the electromagnetic iron, and observe its attraction to the iron block; Press the "up" button to raise the electromagnet; Control the handle and move the electromagnet to the designated area; Press the 'Release' button and observe the iron block falling.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
