Step 1

Given: - Velocity of the rod, v = 8.80 m/s - Magnetic field, B = 0.90 T - Length of the rod, L = 0.50 m Using the formula for induced emf, E = vBL, we can calculate: E = 8.80 * 0.90 * 0.50 E = 3.96 V Therefore, the magnitude of the emf induced in the rod is Show more…

The conducting rod ab shown in makes frictionless contact with metal rails ca and db. The apparatus is in a uniform magnetic field of 0.90 T, perpendicular to the plane of the figure. Find the magnitude of the emf induced in the rod when it is moving toward the right with a speed 8.80 m/s. In what direction does the current flow in the rod? If the resistance of the circuit abcd is a constant 1.50 Ω, find the magnitude of the force required to keep the rod moving to the right with a constant speed of 8.80 m/s. What power is supplied by the force determined in (c)?
