is theory states that the electrons in each atom that make up the metal are believed to be spinning while revolving around the atoms nucleus. Each electron spins around an axis through its center. In a magnetic substance like iron, more electrons spin in one direction than the other within each atom. In a nonmagnetic substance like copper or aluminum, the electrons spins cancel each other out; that is the spins in one direction are more or less compensated by spins in the opposite direction. So, in the iron, more electricity is produced, causing more magnetism.The space around a magnet is different from the space around an unmagnetized object. Michael Faraday (the same man who made the first electric generator) regarded the space around a magnet, called the magnetic field, as being in a state of stress. Because of this, a magnetic field exerts a force on any magnetic pole within its space. Lines of force are imagined as coming out from the north pole of a magnet and passing the south pole of the same magnet in a curved path. These imaginary lines are used to show the direction of the magnetic effect. The lines of force are most concentrated where the magnetic field is most intense.These are just some of the facts known about magnetism today. Hopefully it has now become clearer to you as to what magnetism is and where it originated. You also should understand now that magnetism had a lot to do with much of the technology that is present today and without it, this technology may never have even been thought of....
