Magnetic Field inside a Very Long Solenoid

The solenoid has length L, diameter D, and n turns per unit length with each carrying current .It is usual to assume that thecomponent of the current along the z axisis negligible.(This may be assured by winding two layers of closely spaced wiresthat spiral in opposite directions.)From symmetry considerations it is possible to show that farfrom the ends of the solenoid, the magnetic field isaxial.Which figure shows the loop that the must beused as the Ampèrean loop for finding Bz(r) for...

There is a solenoid (infinitely long) that is filled with a ferromagnetic material. The magnitization, N is uniform and is parallel to the axis of the solenoid. Made out of a nonmagnetized material there is a conducting oval loop. I put the loop around the solenoid. Find the mutual inductance of the solenoid and the loop. I remove the magnetic core. Find the mutual inductance of the solenoid and the loop.

To apply Ampère's law to find the magnetic field inside an infinite solenoid. In this problem we will apply Ampère's law, written ∮B⃗ (r⃗ )⋅dl⃗ =μ0Iencl, to calculate the magnetic field inside a very long solenoid (only a relatively short segment of the solenoid is shown in the pictures). The solenoid has length L, diameter D, and n turns per unit length with each carrying current I. (Figure 1) It is usual to assume that the component of the current...
