Problem 1: Magnetic Field (10 pts.) The infinite straight wire shown in the accompanying figure carries a current $I_1=10\mathrm{A}$. The rectangular loop is carrying a current ${\mathrm{I}}_2=15\mathrm{A}$. What are the magnitude and direction of the force on the rectangular loop due to magnetic field of the wire? Take $a=30\mathrm{cm}$ and $b=20\mathrm{cm}$.
