Consider a closed electric circuit consisting of a conducting straight rod connected to a DC voltage source switched on. In steady state the current flowing through the conductor creates a steady magnetic field around it with magnetic flux lines that can be represented as concentric circles "gripping" around the conductor.
My doubt is that if this conductor (or the entire circuit system) is physically moved randomly about, won't there be a variation in the magnetic field around the conductor (although the source of this magnetic field is the current through the conductor itself)? And, if yes, won't this variation in magnetic field around the conductor self induce an emf in the conductor itself (a case of electromagnetic induction)?
