When the current flows along the wire from A to B, the direction of the lines of force was right-handed, or in the direction of the motion of the hands of a clock, as shown by the curved arrow ; when the current flowed from B to A, the direction of the lines of force was lefthanded, or counter clock-wise. Or, to state it differently, if a person looks along a conductor in the direction in north-seeking, pole of a...

The difference in the pitch of tones is due in the first place to the number of vibrations performed by the vocal chords in a given time ; the greater the number of vibrations, the higher is the tone produced. While E is produced by 80 vibrations in the second, 1024 vibrations are required in the same period to give c'".
