A voltage of 1.50 V is induced in a 30.0 m wire moving perpendicularly through a magnetic field of 3.50×10–3 T, resulting in a calculated speed of 14.2 m/s. The discussion explores the forces acting on the charges within the wire, specifically the magnetic force (Fm) and the electric field (E) that counteracts it. The relationship between electric field and voltage is highlighted, suggesting that the voltage difference can be derived from the integral of the electric field over the wire's length. The user seeks to determine the electric field but struggles with the variables involved, particularly the charge (q) and its relation to the wire's length. The conversation emphasizes the interplay between voltage, magnetic fields, and the motion of the wire.
