Assertion: Free electron 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.
Reason: The average velocity of free electron is zero.

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.

No force acts on a current carrying conductor in a magnetic field when angle between current and magnetic field is

An electron is moving along X-axis in a magnetic field acting along Y-axis. What is the direction of magnetic field acting on it?

If an electron is going in the direction of magnetic field vecB with the velocity of vecv then the force on electron is
