    No magnetic field does not do work. As it is written in question itself that it is an ELECTRO-Maganet. It has both electric field and magnetic field. We know by Maxwell's law that changing electric field induces magnetic field and vice versa. So in this given situation, it is the electric field which does work. It is electromagnet so we provide electricity to it, it is that electricity which do work and not the magnetic field.
