Magnetic Fields

Electronic motors are made with magnetic fields.  The magnetic field is between the field magnet and the armature.  These magnetic fields are formed with electric currents or, "the rate of charge flow past a given point in an electric circuit. (hyperphysics.phy-astr.gsu.edu)"  Each magnet has two ends or poles.  These two poles are the north pole and the south pole, each  specific in its magnetic attractions.  Sometimes, one might find that two magnets refuse to stick together.  This is not because they are special, one-of-a-kind magnets rather their two similar poles are being brought closer together.  What this means is that the south pole of one magnet, and the south pole of another with not attract each other.  However, if opposite poles are brought close together, they will attract each other.

The zone of the attracting or repelling poles is the magnetic field.  There are such things as permanent and temporary magnets.  A permanent magnet will continue to hold its magnetic poles, even if it is not in contact with another magnet.  Temporary magnets are objects such as  paper clips that become magnets only when in the region of another magnet's magnetic field.  This is proven thorough the fact that paper clips do not attract each other when by themselves.  The paper clips is made into a magnet, with both of the correct poles.

These magnetic charges are connected to electricity.  Every atom contain negatively charged electrons and positively charged nucleus.  When atoms have less electrons than usual, they become positive (+).  That being said, when atoms have more than the normal amount of electrons, they become negative (-).  Two positive, or two negative, atoms will push away from each other.  Like magnets, oppositely charged atoms will pull towards each other. 

Around 1800, scientists discovered that electric charges were created "when the ends of a chemical 'battery' were connected by a metal wire. (Dr. David P. Stern)"  The charges networked through the connected wire, heating the wire along the way.  This is now known today as electric currents.
