The figure shows two long, parallel current-carrying wires. The wires carry equal currents I1 = I2 = 20 A in the directions indicated and are located a distance d = 0.5 m apart. Calculate the magnitude and direction of the magnetic field at the point P that is located an equal distance d/2 from each wire. (?0 = 4? × 10^-7 T · m/A)

The two long, parallel wires shown in the accompanying figure carry currents in the same direction. If $I_{1}=10 \mathrm{A}$ and $I_{2}=20 \mathrm{A}, \quad$ what is the magnetic field at point P?
Two long, parallel wires carry currents of $I_{1}=3.00 \mathrm{A}$ and $I_{2}=5.00 \mathrm{A}$ in the direction indicated in Figure $\mathrm{P} 19.50$ . (a) Find the magnitude and direction of the magnetic field at a point midway between the wires $(d=20.0 \mathrm{cm}) .$ (b) Find the magnitude and direction of the magnetic field at point $P$ , located $d=20.0 \mathrm{cm}$ above the wire carrying the 5.00 -A current.
