Magnetism

Magnetism is a force that acts at a distance and is caused by a magnetic field. This force strongly attracts ferromagnetic materials such as iron, nickel and cobalt. In magnets, the magnetic force strongly attracts an opposite pole of another magnet and repels a like pole. The magnetic filed is both similar and different to an electric field. The lines of magnetic flux flow from one end of the object to the other. Although individual …

…a permanent magnet; however, the magnetic fields of the individual atom are aligned in one preferred direction, giving rise to a net magnetic field. In fridge magnets there are domains in which the magnetic fields of the individual atoms align, but the orientation of the magnetic fields of the domains is random, giving rise to no net magnetic field. Then we concluded that magnetism is essential for our lives and also makes things much easier.
