   Without an iron core of some sort I doubt if there's much risk.   
   However wiring regulations require that mains carrying cables should   
   be either 50mm away from low voltage ones or that there should be   
   'mechanical separation' between mains and low voltage wiring. (That's   
   the basics anyway).
