2018/8/18 the magnetic field around an electromagnet is just the same as the one around a bar magnet it can, however, be reversed by turning the battery around unlike bar magnets, which are permanent magnets, the magnetism of electromagnets can be turned on and off just by closing or opening the switch. 2000/4/1 how electromagnets work by marshall brain & lance looper diy electromagnets and experiments to try prev presto a working electromagnet [source: jefferson lab] can't get enough of hands-on electromagnetic experiments we have some more ideas. Note: making an electromagnet uses up the battery somewhat quickly which is why the battery may get warm, so disconnect the wires when you.
