If you want to get REAL technical, there is an answer;
Since there is a magnetic field accompanying ALL elelctrical circuits, there is also an (electro)magnetic field in the wiring to the coil. This said, You will notice that when a person lives in the Northern Hemisphere that water runs down a drain in a clockwise direction. This is only partly due to the Coriollis Effect of the spinning of the earth, but also the magnetic or Capillary Attraction Effect too, as the water comes into contact with an easily covalently-bonded other substance. Additionally, there is a Magnetic Attraction Effect that plays a small role in how the coil should be wound around the pole.
In short, if you live in the Northern Hemisphere, you should wrap it clockwise, the same direction of the twirling water in your kitchen drain, and if you live in the southern hemi, it should be wrapped the opposite direction, counter-clockwise. Yes, this is basic physics, but still applicable and useful because it will assist in proper alignment or misalignment of the "hole theory" of electronics, one that requires the best and easiest path or least resistance of magnetically charged low-voltage wiring. Additionally, there is a condensor or balon effect in play anytime that a wire is "coiled". Remember too, that there is no such thing as a completely insulated set of wiring. Even something enveloped in six feet of plastic can still leak electrons. And yes, even plastic carries electricity to at least some degree. So does air.
