Direction of the electric current

(B) According to the Right-Hand Thumb Rule,if you hold a current-carrying straight conductor in your right hand such that your thumb points in the direction of the current,then your fingers will wrap around the conductor in the direction of the magnetic field lines. Therefore,the direction of the magnetic field is determined by the direction of the electric current flowing through the wire.
