Exam II solutions
... Solution: The force acting on the metal bar is F = iLB = ELB / R . The bar will accelerate until the induced emf Eind = vLB is equal to the battery emf, when the current and thus the force becomes zero. Thus the maximum velocity is v = E / LB = 12 / ( 0.30 ! 0.25) = 160 m/s. 13. A long straight wire ...
