A magnetic field flows from a north pole to a south pole. A magnetic field line shows the direction in which
would feel a force. Only some materials are attracted to a magnet, such as
.
Some magnets produce their own magnetic field all the time; these are known as magnets. Others only become magnetic when placed in a magnetic field; these are known as magnets.
A wire carrying a current produces a magnetic field; the magnetic field lines . 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; turns this into an electromagnet and increases the strength of the magnetic field produced.
