Product Details
Note: The wire color is randomly selected. This 5V DC sucker type electromagnet is a real powerhouse! It boasts a 30Kg holding force and only consumes 3W of power. You can easily change its magnetic poles by swapping the positive and negative poles of the input power. Despite its compact size, it's incredibly versatile. You can use it for DIY electromagnetic locks, smart storage cabinets, intelligent doors, and more. An electromagnet is typically made of a wire coil wrapped around an iron core. When current flows through the coil, it creates a magnetic field that magnetizes the iron core, just like a permanent magnet. The iron core is made of pure iron or silicon steel, which can be easily magnetized and demagnetized. So, it becomes magnetic when powered on and loses magnetism quickly when powered off. Here are some important points to note. First, the 'holding force' of 30Kg doesn't mean it can pick up a 30Kg object. You should divide the holding force by 5 - 10 to get an approximate pick - up weight, which is about 6Kg in this case. The pick - up weight also depends on a flat surface, maximum surface contact, and the ferromagnetic metal content. A flat steel cube works best, while oddly shaped or rubber/plastic - covered objects won't work well. Second, the electromagnet can be energized for a long time when it's attracted to an object's surface, but avoid long - term energization when there's nothing to attract. Specification: Rated Voltage: DC 5V; Rated Power: 3W; Holding Force: 30Kg; Wire Length: 28cm. Shipping List: One 5V Electromagnet (30Kg Holding Force) and One Mounting Screw.
Using this 5V electromagnet is quite straightforward. First, connect it to a 5V DC power source. Make sure to check the positive and negative poles correctly. If you want to change the magnetic poles, just swap the connection of the power poles. This electromagnet is great for DIY projects like making electromagnetic locks or smart storage cabinets. When it comes to picking up objects, remember that the 30Kg holding force is not the actual weight it can pick up. Divide the holding force by 5 - 10 to get a rough estimate, so around 6Kg maximum. Also, the object should have a flat surface and high ferromagnetic metal content for the best results. When the electromagnet is attracted to an object, it can be energized for a long time. But don't keep it energized for long when there's no object to attract, as it may cause unnecessary wear. As for maintenance, keep it clean and dry. Check the wire regularly for any signs of damage. If you notice any issues, replace the wire promptly to ensure its proper functioning.
