5V Electromagnet (20 Kg Holding Force)

Note: The wire color is randomly assigned. This 5V DC sucker - type electromagnet has a 20kg holding force and only consumes 1.5W of power. With its compact design, it's perfect for DIY electromagnetic locks, smart storage cabinets, and intelligent doors. You can easily switch the magnetic poles by reversing the input power's positive and negative terminals. An electromagnet usually consists of a wire coil around an iron core. When current flows, it magnetizes the core, just like a permanent magnet. The core is made of pure iron or silicon steel for easy magnetization and demagnetization, meaning it magnetizes when powered on and quickly loses magnetism when powered off. Remember, the 'holding force' (20kg here) isn't the pick - up weight. Divide it by 5 - 10 to estimate the pick - up weight (around 4Kg max in this case). The pick - up weight also depends on a flat surface, maximum surface contact, and ferromagnetic metal content. It can withstand long - term electrification when attached to an object, but don't keep it powered for long when there's nothing to attract. Specification: Rated Voltage: DC 5V; Rated Power: 1.5W; Holding Force: 20kg; Wire Length: 28cm. Shipping List: One 5V Electromagnet with 20 Kg Holding Force and one Mounting Screw.

Using this electromagnet is easy. First, connect it to a 5V DC power source. You can reverse the power's positive and negative terminals to change the magnetic poles. It's great for DIY projects like making electromagnetic locks or smart storage cabinets. When it comes to the pick - up weight, don't rely on the holding force. Divide the 20kg holding force by 5 - 10 to get a rough idea of what it can pick up, around 4Kg max. Make sure the object has a flat surface and enough ferromagnetic metal content. You can keep it powered on for a long time when it's attracted to an object. But don't leave it electrified when there's nothing to hold. As for maintenance, keep it clean and dry. Avoid exposing it to extreme temperatures or humidity. If you notice any problems, check the connections and power source.
