###### A uniform, $458-mathrm{g}$ metal bar $75.0$ Figure P7.47 $mathrm{cm}$ long carries a current $I$ in a uniform, horizontal $1.25-mathrm{T}$ magnetic field as shown in Fig. P7.47. The directions of $I$ and $overrightarrow{oldsymbol{B}}$ are shown in the figure. The bar is free to rotate about a frictionless hinge at point $b .$ The other end of the bar rests on a conducting support at point $a$ but is not attached there. The bar rests at an angle of $60.0^{circ}$ above the horizontal. What is the

A uniform, $458-mathrm{g}$ metal bar $75.0$ Figure P7.47 $mathrm{cm}$ long carries a current $I$ in a uniform, horizontal $1.25-mathrm{T}$ magnetic field as shown in Fig. P7.47. The directions of $I$ and $overrightarrow{oldsymbol{B}}$ are shown in the figure. The bar is free to rotate about a frictionless hinge at point $b .$ The other end of the bar rests on a conducting support at point $a$ but is not attached there. The bar rests at an angle of $60.0^{circ}$ above the horizontal. What is the largest value the current $I$ can have without breaking the electrical contact at $a$ ? (See Problem 7.77.)
