As a summer intern at a research lab, you are given a long solenoid that has two separate windings that are wound close together, in the same direction, on the same hollow cylindrical form. You must determine the number of turns in each winding. The solenoid has length L= 35.0 cm and diameter 2.80 cm. You let a 2.00-mA current flow in winding 1 and vary the current I in winding 2, both currents flow in the same direction. Then you measure the magnetic-field magnitude Bat the center of the solenoid as a function of I. You plot your results as BL/40 versus I. The graph in (Eigure 1) shows the best-fit straight line to your data.

Question
As a summer intern at a research lab, you are given a long solenoid that has two separate windings that are wound close together, in the same direction, on the same hollow cylindrical form. You must determine the number of turns in each winding. The solenoid has length L= 35.0 cm and diameter 2.80 cm. You let at 2.00-mA current flow in winding 1 and vary the current I in winding 2; both currents flow in the same direction. Then you measure the magnetic-field magnitude B at the center of the solenoid as a function of I. You plot your results as BL/μo versus I. The graph in (Figure 1) shows the best-fit straight line to your data. Figure < 1 of 1 1 (mA) BL/μg (A) 16.00 12.00 8.00 4.00 0.00 0.00 1.00 2.00 3.00 4.00 5.00 6.00 ▼ Part A Why the data plotted in this way should fall close to a straight line? Select the correct explanation below. O The ratio BL/o has linear dependence on number of turns. O The ratio BL/μo has linear dependence on the product of the currents in both windings. O The ratio BL/Ho has linear dependence on current. Submit Request Answer Part B Use the graph to calculate the number of turns in winding 1. Express your answer using three significant figures.
