The Grove Electromagnet is a type of magnet in which the magnetic field is produced by electric current. The Grove Electromagnet can hold 1kg weight. It easy to use, to learn electromagnet principles.
Works well - the board provides the necessary transistor, protection diode and resistors so no additional components are required. Note that you don't need a GrovePi kit or anything to make this work, just connect it to a 5V supply, ground and logic input as indicated. Works fine with a 3.3V logic signal (e.g. from a Raspberry Pi).

Correct product
Works great, heats a little. I test it with a 0,5kg cylinder. I can pull it, but not lift it.

Works well, but not strong
A nice module, but only strong when directly contacting ferrous material. I tried putting a 0.2mm ABS cover over it and it effectively couldn't hold more than a paperclip.
