Question

Figure (a) shows, in cross section, two long, parallel wires carrying current and separated by distance L. The ratio of their net their currents is 6.20: the directions of the currents are not indicated. Figure (b) shows the y component B, of their net magnetic field along the x axis to the right of wire 2. The vertical scale s set by B_ = 2.0 nT, and the horizontal scale is set by x_ = 22.2 cm. (a) At what value of x > 0 is B_ maximum, (b) If i_2 = 3.28 mA, what is the value of that maximum? What is the direction (into or out of the page) of (c) and (d) i_2? (cm) (a) Number Units (b) Number Units (c)

Explanation / Answer

(a)As seen clear from the graph,maximum B=14 nT toward -y axis at x=22.2 cm

(b) As seen from the graph ,maximum value of B=14 nT

(c ) direction of I1=out the page

(d) direction of i2=into the page
