A conducting bar of length moves to the right on two frictionless rails, as shown in the figure below. A uniform magnetic field directed into the page has a magnitude of 0.3 T. Assume ℓ = 51 cm and R = 10 Ω and a current of 7.8 mA in the resistor. (c) At what rate is energy delivered to the resistor? (d) What is the strength of the magnetic field due to the induced current? (e) Find the magnitude of the force applied?
