5V Electromagnet (25 Kg Holding Force)

Note: The wire color is randomly assigned. This DC sucker-type electromagnet has a 25kg holding force and 1W power, operating at 5V. You can change its magnetic poles by reversing the input power's positive and negative poles. Despite its small size, it's great for DIY electromagnetic locks, smart storage cabinets, and intelligent doors. An electromagnet typically consists of a wire coil around an iron core. When current flows through the coil, it creates a magnetic field that magnetizes the iron core, similar to a permanent magnet. The core is made of pure iron or silicon steel for easy magnetization and demagnetization, so it becomes magnetic when powered on and loses magnetism quickly when powered off. Keep in mind: 1. The 'holding force' (25kg here) isn't the weight it can pick up. Divide the holding force by 5 - 10 for a rough pick - up weight estimate, around 3kg max in this case. Pick - up weight also depends on a flat surface, maximum surface contact, and ferromagnetic metal content. A flat steel cube works well, while oddly - shaped or rubber/plastic - covered objects don't. 2. The electromagnet can be electrified for a long time when attached to an object's surface, but avoid long - term electrification when there's nothing to attract. Specification: Rated Voltage: DC 5V; Rated Power: 1W; Holding Force: 25kg; Wire Length: 28cm. Shipping List: One 5V Electromagnet (25 Kg Holding Force) and one Mounting Screw.

Using this electromagnet is easy. First, make sure to connect it to a 5V DC power supply. You can change the magnetic poles by swapping the positive and negative connections. It's great for DIY projects like making electromagnetic locks or adding to smart storage cabinets. When it comes to picking up objects, remember that the 25kg holding force doesn't mean it can lift 25kg. Divide the holding force by 5 - 10 to get a rough idea of what it can pick up. Try to use flat, ferromagnetic objects for the best results. When the electromagnet is attracting an object, it can be powered on for a long time. But don't leave it powered on when there's nothing to attract. To keep it in good shape, avoid over - electrifying it. And that's all you need to know to use and take care of this electromagnet.
