Is there any loss of Electrical Energy due to the Magnetic Field around a current carrying conductor?How?
Basically Electric & Magnetic field are always associated; one can’t be without the other. In DC where the frequency is zero, there won’t be any radiation. Even a steady current if interrupted, it amounts to a whole lot of different frequencies superimposed (i.e.alternating current). In non-DC (or AC of any frequency) the circuit is prone to radiate if there is another circuit that can ‘load’ (absorb) it. This can be a lose wire forming a closed loop, whose resistance happens to be the load, thus coupled to the main current. The ratio of Electric field generated (E) to the magnetic field (H) depends on the medium. If it is high it manifests as Electric circuit, or if low it is seen & felt as magnetic circuit, ignoring the very low electric effect. Even the coupled circuit itself should have the same ratio for a smooth flow of power to it. The power that is carried away thus (‘loading’ if it is undesirable) consumes electric energy at a steady rate (per unit time). Whether it is a loss
