The horizontal portion of the wire in Figure P28.76 has a length \(\ell=0.100 \mathrm{~m}\), and position \(\mathrm{P}\) is a perpendicular distance \(d=30.0 \mathrm{~mm}\) above the center of the horizontal portion. The wire carries a \(45.0-\mathrm{A}\) current, and the two slanted portions of the wire are extremely long. Calculate the magnitude of the magnetic field at P.
