A $0\mathrm{.}850-$m$-$long metal bar is pulled to the right at a steady $5\mathrm{.}0$ m$/$s perpendicular to a uniform, $0\mathrm{.}550-$T magnetic field. The bar rides on parallel metal rails connected through a $25-$

$,$ resistor $,$ so the apparatus makes a complete circuit. Ignore the resistance of the bar and the rails.
