A magnetic field flows from a north pole to a south pole. A magnetic field line shows the direction in which  an electrona north polea south poleboth polesa magnetic materiala proton would feel a force. Only some materials are attracted to a magnet, such as  gold and silveriron and nickelcopper and aluminiumhydrogen and heliummagnesium and manganesecarbon and oxygen.
Some magnets produce their own magnetic field all the time; these are known as  barhorseshoeinducedpermanentsolenoidmotor magnets. Others only become magnetic when placed in a magnetic field; these are known as  solenoidpermanentmotorhorseshoebarinduced magnets.
A wire carrying a current produces a magnetic field; the magnetic field lines  move in circles around the wire, along its entire lengthpoint directly out of the wirerun parallel along the length of the wireflow from one end of the wire to the othermove in circles around the wire at certain pointspoint directly into the wire.  A transformerAn induced magnetA solenoidA permanent magnetA permanent magnetAn electromagnet is a current-carrying wire wrapped into a long coil, so that the magnetic field lines are in the same shape as those for a bar magnet;  adding an iron core in the middleincreasing the currentincreasing the number of coilsadding another coilreversing the direction of the currentcoating the wire in plastic turns this into an electromagnet and increases the strength of the magnetic field produced.
