This is a remarkable DC sucker type electromagnet! It has a 35kg holding force and runs on 3W power at 5V. You can easily change its magnetic poles by swapping the input power's negative and positive poles. With its compact body, it's perfect for DIY electromagnetic locks, smart storage cabinets, and intelligent doors. Electromagnets are made of a wire coil around an iron core. When current passes through the coil, it creates a magnetic field, magnetizing the iron core like a permanent magnet. The iron core is made of pure iron or silicon steel, which can be quickly magnetized and demagnetized. So, it becomes magnetic when powered on and loses magnetism right after power - down. Note: The 'holding force' of 35Kg doesn't mean it can pick up 35Kg. Divide the holding force by 5 - 10 to estimate the pick - up weight, which is about 7 Kg max here. The pick - up weight 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. Also, it can withstand long - term electrification when attracted to an object's surface, but don't keep it electrified for long when there's nothing to attract. Specification: Rated Voltage: DC 5V; Rated Power: 3W; Holding Force: 35kg; Wire Length: 28cm. Shipping List: One 5V Electromagnet with 35 Kg Holding Force and one Mounting Screw.
Using this electromagnet is easy. First, connect it to a 5V DC power supply. To change the magnetic poles, just swap the positive and negative wires. You can use it for your DIY projects like making an electromagnetic lock or a smart storage cabinet. When using it to pick up things, remember the pick - up weight is about 7 Kg max. Make sure the object has a flat surface and enough ferromagnetic metal content. Don't try to pick up oddly - shaped or rubber/plastic - covered objects. When the electromagnet is attracting an object, it can be electrified for a long time. But when there's no object to attract, don't keep it electrified for too long to avoid damage. For maintenance, keep it dry and clean. If there's dust on it, you can gently wipe it with a dry cloth.
