Michael Faraday unsuccessfully attempted to measure the
potential difference across the River Thames due to the flow of
water (which is a good conductor due to dissolved salts) in the
earth's field. At Waterloo Bridge, where Faraday made his attempt,
the river is 200 m wide and flows eastward at 2.4m/s . The earth's
magnetic field here has a magnitude of 50 *?*T and is tipped
65?from the horizontal, so it has both horizontal (north) and
vertical (down) components.

**Part B**
