Electromagnets are made from wire with an electric current being wrapped around a magnetic object. To strengthen an electromagnet you can coil the wire around the magnetic object, or to further strengthen- add an iron core instead of a normal magnet. They have the same magnetic fields as bar magnets, except they can be reversed and turned off.
