5V Electromagnet (8 Kg Holding Force)

Note: The wire color is random. This 5V DC sucker - type electromagnet has an 8kg holding force and 1.5W power. It's super compact and perfect for DIY electromagnetic locks, smart storage cabinets, and intelligent doors. By swapping the input power's positive and negative poles, you can change its magnetic poles. Electromagnets typically have a wire coil around an iron core. When current flows, it magnetizes the core like a permanent magnet. The core is made of pure iron or silicon steel for easy magnetization and demagnetization, losing magnetism quickly after power - off. Remember, the 8Kg holding force doesn't mean it can pick up 8Kg. Divide it by 5 - 10 to estimate the pick - up weight, here about 1.6 Kg max. The pick - up weight depends on a flat surface, full contact, and ferromagnetic metal content. It can withstand long - term electrification when attracting an object but not when there's nothing to attract. Specifications: Rated Voltage - DC 5V, Rated Power - 1.5W, Holding Force - 8Kg, Wire Length - 28cm. Shipping includes one 5V Electromagnet with 8Kg Holding Force and one mounting screw.

Using this electromagnet is easy. First, make sure you connect it to a 5V DC power source. If you want to change the magnetic poles, just swap the positive and negative connections of the power input. You can use it for various DIY projects like making an electromagnetic lock or adding it to a smart cabinet. When it comes to picking up things, don't expect it to lift 8Kg. Divide the 8Kg holding force by 5 - 10 to get a rough idea of the weight it can handle, around 1.6 Kg max. Also, the object should have a flat surface and a good amount of ferromagnetic metal. Avoid using it on oddly - shaped objects or those covered in rubber or plastic. The electromagnet can be powered on for a long time when it's attracting something. But don't leave it powered on when there's nothing to attract, as it might cause issues. As for maintenance, there's not much to do. Just keep it clean and away from moisture. And if you need to mount it, use the included mounting screw.
