5V Electromagnet (3Kg Holding Force)

This is a fantastic DC sucker type electromagnet! It has a holding force of 3 kg and a power of 1W, and it operates at 5V. You can easily change the magnetic poles by swapping the negative and positive poles of the input power. With its compact size, this electromagnet is perfect for DIY electromagnetic locks, smart storage cabinets, intelligent doors, and more. An electromagnet typically consists of a wire coil wrapped around an iron core. When current passes 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 is easy to magnetize and demagnetize. So, it becomes magnetic when powered on and loses magnetism quickly after power - down. Note: The 'holding force' of 3 kg doesn't mean it can pick up 3 kg. Divide the holding force by 5 - 10 to estimate the pick - up weight, which is about 0.6 kg 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. The electromagnet can withstand long - term electrification when attracted to an object's surface, but don't keep it electrified for a long time when there's nothing to attract. Specifications: Rated Voltage is DC 5V, Rated Power is 1W, Holding Force is 3 kg, and Wire Length is 28 cm.

Using this electromagnet is easy. First, make sure to connect it to a 5V DC power source. You can switch the magnetic poles by changing the connection of the positive and negative poles of the power. This electromagnet is great for DIY projects like making an electromagnetic lock or adding to a smart storage cabinet. When using it to pick up things, remember that the 3 kg holding force doesn't mean it can lift 3 kg. Divide the holding force by 5 - 10 to get a rough idea of the pick - up weight, and choose flat, ferromagnetic objects for the best results. When the electromagnet is attracted to an object's surface, it can be electrified for a long time. But don't keep it powered when there's nothing to attract, as this may cause damage. To maintain it, keep it dry and clean, and avoid over - heating. That's all you need to know to use this electromagnet effectively!
