    According to the biot savart law , the magnet field at a point around conductor (B) =kIdlsin₩/r2 Where k=constant of proportionality I=current, dl=small elementary length of conductor ₩= angle between I & dl The magnetic field inside a condutor is 0 Because angle (₩ ) between I&dl is 0 Therefore sin0=0 Thus b unside a conductor is 0

    Subani ji this is magnetic field not electric field so no role of electrons in this

    1Thank You
