Step 1
0 \, \text{A}$ is the current in the first wire, $r = 0.5 \, \text{cm} = 0.005 \, \text{m}$ is the distance from the wire to point $P$, and $\mu_0 = 4\pi \times 10^{-7} \, \text{Tm/A}$ is the permeability of free space. ** Show more…

Point $P$ is midway between two long, straight, parallel wires that run north-south in a horizontal plane. The distance between the wires is $1.0 \mathrm{cm} .$ Each wire carries a current of $1.0 \mathrm{A}$ toward the north. Find the magnitude and direction of the magnetic field at point $P$.
Point P is midway between two long, straight, parallel wires that run north-south in a horizontal plane. The distance between the wires is 2.1 cm. The wire on the west carries a current of 2.0 A toward the north, and the wire on the east side carries the same amount of current but runs toward the south instead. Find the magnitude and direction of the magnetic field at point P. Show work please thanks!

A long, straight wire lies along the $y-$axis and carries a current $I =$ 8.00 A in the $-y$-direction ($\textbf{Fig. E28.21}$). In addition to the magnetic field due to the current in the wire, a uniform magnetic field $\overrightarrow{B}_0$ with magnitude 1.50 $\times$ 10$^{-6}$ T is in the $+x$ direction. What is the total field (magnitude and direction) at the following points in the xz-plane: (a) $x =$ 0, $z =$ 1.00 m; (b) $x =$ 1.00 m, $z =$ 0; (c) $x =$ 0, $z = -$0.25 m?
