Question
The figure shows a metallic block, with its faces
parallel to coordinate axes. The block is in a uniform
magnetic field of magnitude 0.021 T. One edge
length of the block is 23 cm; the block is not drawn to
scale. The block is moved at 2.9 m/s parallel to each
axis, in turn, and the resulting potential difference V
that appears across the block is measured. With the
motion parallel to the y axis, V = 18 mV; with the
motion parallel to the z axis, V = 12 mV; with the
motion parallel to the x axis, V = 0. What are the
block lengths (a) dx, (b) dy, and (c) d₂?
