(Solved): Calculate the magnitude of the emf induced in the circuit. Find the direction of the current induced ...

A 0.850-m-long metal bar is pulled to the right at a steady $6.0\mathrm{m}/\mathrm{s}$ perpendicular to a uniform, $0.650?\mathrm{T}$ magnetic field. The bar rides on parallel metal rails connected through a $25??$, resistor (Figure 1), so the apparatus makes a complete circuit. Ignore the resistance of the bar and the rails.
