The 'why' of electromagnetic induction

  1. Aug 24, 2009 #1
    Are electromagnetic waves always caused by a moving charge? A magnetic field can induce current in a conductor if the magnetic flux going through this conductor changes, is this reversible? So does an electric field cause a magnetic field because the electric flux ('through' what?) changes? Is there an intuitive understanding of this phenomena?

    Yes, the way to understand this is Maxwell equations, there you can see the symmetry between electric and magnetic fields :)

    There you can see that: a flux of electric field causes a rotational magnetic field, and a flux of magnetic field causes a rotational electric field.

    And there also you can do some assumptions about "magnetic charges" if you wish :D, heheheh. Some fancy imagination ;)

    If you have some specific question, just ask :)
