Electro Magnetics

  1. Feb 23, 2006 #1
    Sir,
    When a current is passed through a conductor, a magnetic field is produced around it. Due to the flowing charges, is an electric field also produced around the conductor?

    You might have to think just about when, how and where is and electric field is formed. Has magnetic effect of current flowing through a conductor anf those forces started for you. Then you must understand the following. Probably you read H C Verma or Resnick Halliday for better understanding. You can even refer to the NTSC CBSE 11-12th textbooks. The explanation is in simple english there.

    yes there is also an electric field. that's why power lines humm because of the huge potential they have relative to the air and the effect it has on the moisture
