The DFRobot 5V Electromagnet (35kg Holding Force) is a DC sucker type electromagnet with 35 kg holding force and 3 W power. It should be operated at 5 V.
The magnetic poles of the electromagnet can be changed by swapping the negative and positive poles of the input power. With a pretty small body, this electromagnet can be applied to a DIY electromagnetic lock, smart storage cabinet, and intelligent door, etc.
Electromagnetic usually consists of a coil of wire wrapped around an iron core. When currents pass through the wire coil, a magnetic field, which makes the iron core magnetized, like a permanent magnet.
The iron core material should be made of pure iron or silicon steel which is easy to be magnetized and demagnetized. In this way, it will be magnetic when powered on and lose magnetism quickly after power-down.
