Is there any Limit to the size you can make an electromagnet or if you have a large enough power source and enough insulated wire, can you make a larger one?


Electromagnets do reach a state called saturation Where all of the little magnetic domains in the iron core are lined up together and additional current can't increase the strength of the magnetic field. Here is a formal on-line explanation:
