A conducting bar rotates with a constant angular speed in a counterclockwise direction about a pivot at one end as shown. Assume a uniform magnetic field is directed out of the page. Which is the correct statement for describing the potential difference induced along the length of the bar? Rod pivoted at one end A. The potential is maximum at the middle of the bar and lowest at the pivot. B. The potential is higher at the end far away from the pivot and the potential is lower at the pivot. C. The potential difference is zero along the length of the bar. D. The potential is higher at the pivot and lower at the end far away from the pivot.
