Imagine a current carrying wire with the direction of current downward or into the page. The direction of magnetic field lines is
Maxwell's Corkscrew Rule: Imagine a right-handed corkscrew being driven in such a way that it moves in the direction of the current flow. The direction of rotation of the handle then gives the direction of the magnetic field lines.
The motion of an electron in presence of a magnetic field is depicted in the figure.
Force acting on the electron will be directed
