Does static charge near to a constant current carrying conductor experience force on it?
I am asking this question because i have learned that electric field and mangnetic field are same thing but viewing differently with respect to the frame of reference...when a positive test charge moves ( parallel to the wire) near to the current carrying conductor ,with respect to the positive charge positive ions in the conductor are moving and due to length contraction charge density due to positive ions will be higher so net electric field will be present. that will repel the test charge... So magnetic field in the rest frame is actually electric field in the test charge's moving frame..i am ok with this .but consider when that test charge at stationary position ,it sees the length contraction of electrons ( which are moving) ... So there will be an attractive electrical force ...but if I think like the following,wire is actually neutral because at a time,number of electrons enter into the wire equal to number of electrons leave ...so in that way static test charge will not experience any force. I feel contradiction...help me
I am repeating my question, electric field due to current carrying conductor is zero or not??
