Solution

Question\n\nConsider a conducting rod of length $l$ moving with velocity $v$ to the right as shown in the figure. Left ends of the conducting rails are connected to a bulb. Due to motion of the rod through the magnetic field, an emf is produced across the ends of the rod. This emf gives rise to a current $I$. As a result, the bulb lights up. Explain where does the electrical energy consumed by the bulb come from?\n\nContent coming soon. Write the full solution here, or use the part files (p-i.mdx, p-ii.mdx, …) for each part.
