This is an electromagnet with a holding force of 35 kg and a power of 3 W. The magnetic poles of the electromagnet can be changed by swapping the negative and positive poles. The holding force does not indicate how much weight it can support. Divide the holding force by 5-10 to get a rough estimate of how heavy an object it can attract and hold. In this case, that would be a maximum of about 7 kg. Note that the holding weight also depends on a flat surface, the maximum surface contact, and the ferromagnetic metal content. The electromagnet can withstand long-term electrification when attracted to the surface of an object. However, it should not be electrified for a long time if there is nothing to attract.
