Magnetic Circuits

  1. Jul 6, 2010 #1
    While reading my text about the differences between the electrical and magnetic circuits, there was one point that I couldn't justify myself with.

    ... There is no waste of energy due to reluctance in a magnetic circuit and therefore energy is required only to create a magnetic flux but not to maintain it, unlike the electrical circuits.

    Can anyone explain me or let me have a better picture of this?

    Electric current is the directed motion of charges inside the conductors. Magnetic flux, the analogue of the electric current for magnetic circuits does not represent a flux of particles carrying some kinetic energy.
