Homework Help: Force on a Current Carrying Conductor

  1. Mar 2, 2008 #1
    1. The problem statement, all variables and given/known data

    Which of the following situations would result in a magnetic force on the wire that points due north?

    Check all that apply.

    Current in the wire flows straight down; the magnetic field points due west.
    Current in the wire flows straight up; the magnetic field points due east.
    Current in the wire flows due east; the magnetic field points straight down.
    Current in the wire flows due west and slightly up; the magnetic field points due east.
    Current in the wire flows due west and slightly down; the magnetic field points straight down.

    2. Relevant equations

    Right hand rule of left hand rule

    3. The attempt at a solution

    I know that the third one is correct but it says that the answer is wrong which means there is atleast one other correct answer but I have NO CLUE which one that is. Please help.
