Two long, straight wires, each carrying a current of \( 5 \mathrm{~A} \), are placed along the \( x \) - and \( y \)-axes respectively. The currents point along the positive directions of the axes. Find the magnetic fields at the points (a) \( (1 \mathrm{~m}, 1 \mathrm{~m}) \),
(b) \( (-1 \mathrm{~m}, 1 \mathrm{~m}) \), (c) \( (-1 \mathrm{~m},-1 \mathrm{~m}) \) and (d) \( (1 \mathrm{~m},-1 \mathrm{~m}) \).
