Free electron always keep on moving in a conductor. Even then, no magnetic force acts on them in a magnetic field unless a current is passed through it. Why?

(A) : Free electrons always keep on moving in a conductor even then no magnetic force act on them in magnetic field unless a current is passed through it. (R) : The average velocity of free electron in a conductor is zero in the absence of the electric field in it.
