I hooked an iginition coil up to a battery and, when I disconnected the two, I 
got a spark about a half an inch in length.  This worked as it should but I am 
confused about how it works.  I only get a spark when I break the connection 
between the ignition coil and the power source.  I would appreciate any 
information on why this occurs.
