1. Consider two differential current elements $?I_{1}a_{x}$ located at $r_{1}=(1,0,0)m$ and $?I_{2}a_{y}$ located at $r_{2}=(0,1,0)m$. a) Compute $B_{1}$ due to $?I_{1}a_{x}$ at the location $r_{2}$ of element 2 b) Compute $B_{2}$ due to $?I_{2}a_{y}$ at the location $r_{1}$ of element 1 c) Compute the magnetic force $F_{m,12}$ on element 2 due to element 1 . d) Compute the magnetic force $F_{m,2l}$ on element 1 due to element 2 . e) Discuss $F_{m,l2}$ and $F_{m,2l}$ in terms of Newton's third law. Do the results make sense? Why or why not?
