How to 'see' electric field ?

  1. Aug 1, 2011 #1
    Hi All,

    See, if you place a paper above a magnet and put some iron filings, we can visualize the concept of magnetic field. My question is : Is there any such experiment/technique to really visualize (see) the electric field by a charge ?

    Waiting for comments and discussions...

    Thanks....

    Yes you can see the E field lines with grass seeds in oil.
    Walter lewin does this around the 43 minute mark , but you should watch the hole video.
    And i think he also shows you how an electric dipole acts in an E field.
