Learning Goal: To apply Ampere's law to find the magnetic field inside an infinite solenoid. Which figure shows the loop that the must be used as the Amperean loop for finding Bin (r) for r inside the solenoid? In this problem we will apply Ampere's law, written f B(F) . dl = Ho Tends to calculate the magnetic field inside a very long solenoid (only a relatively short segment of the solenoid is shown in the pictures). The segment of the solenoid shown in (Figure 1) has diameter D, and n turns per unit length with each carrying current I. It is usual to assume that the component of the current along the z axis is negligible. (This may be assured by winding two layers of closely spaced wires that spiral in opposite directions.) From symmetry considerations it is possible to show that far from the ends of the solenoid, the magnetic field is axial.
