... This kind of magnetic field is known as a magnetic dipole. (See diagram on right) Magnets are not the only things that can produce magnetic fields. Moving charged particles such as electrons can also create a magnetic field. A straight line of moving electric charge, in a wire, creates a magnetic fi ...

... The polarity of a magnet, therefore, is defined by the polarity of this magnetic flux. The north pole of a bar magnet is the end which tries to point to the North Pole of the Earth, (the correct full name for the north pole of a bar magnet is “North-seeking pole”). This accepted convention became es ...
