Hello, I am trying to use an Arduino(Mega) to control an electromagnet strength. In the end of the day, I will need to control the strength in 3 levels (High/ Low/ Off), I don't know yet what Voltage I will use for each level (Off is 0V of course). My electromagnet is a 12V electromagnet. the Hig…

Thank you for the response, the current is a direct function of the voltage (V=RI), this is why i AM referring to voltage.
the electromagnet resistance is ~30 Ohm.
I did not found any data sheet, this is the electromagnet:
