Question

8.2 How does $B\left(\frac{a}{2}\right)$, the magnitude of the magnetic field at a distance $r=\frac{a}{2}$ cm from the axis, compare with $B(a)$, the magnitude of the magnetic field at a distance $r=a$ cm from the axis? (2.5 points) $B\left(\frac{a}{2}\right)<B(a)$ $B\left(\frac{a}{2}\right)>B(a)$ $B\left(\frac{a}{2}\right)=B(a)$ You have used 0 of 1 attempt Submit 8.3 Two very long wires are added as shown in the figure below. Each wire carries a current $I=1.0 \mathrm{~A}$ in the $+z$-direction. Each wire is located a distance $d=7 \mathrm{~cm}$ from the x-axis. How does $B(P)$, the magnitude of the magnetic field at point $P$ change? (2.5 points) $B(P)$ increases $B(P)$ remains the same $B(P)$ decreases You have used 0 of 1 attempt Submit
