B) Use the graph to calculate the number of turns in
winding 2. (N2)
C) If the current in winding 1 remains
2.00 mAmA in its original direction and winding 2
has II = 5.00 mAmA in the opposite direction,
what is BB at the center of the solenoid? (B)
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 = 38.0 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 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 - I (mA) BL/μo (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 >
