The rails of a railway track are 1.80 m apart and assumed to be insulated from one another. Calculate the emf induced between the rails if a train is passing at 120 km. `h^(-1)`. Assume that the horizontal component of earth's magnetic field, `H=0.36xx10^(-4)T` and angle of dip. `theta=tan^(-1)(1.026)`.
