Permanent magnet magnetic field is permanent and electromagnets magnetic field depends upon the flow of the electrical current. The electromagnet constitutes a coil made of wire which acts as a magnet when current is passed through it. Usually a ferromagnetic material like steel is wrapped by an electromagnet to enhance its magnetic field.
