on a Self- and mutual - inductance coefficients of long solenoids. this is a very simple problem single long solenoid and two concentric long solenoids. Consider a long solenoid with n = 100 loops per deci- I meter of lenght °(1 decimeter Cem )=104m) and loop ross-section S= 100 cm 1) Calculate the self-inductance I per urut lenght of the solenoid. 2) Consider to insert a second long solenoid inside the first solenoid and coaxial with it Caf. rig.

Learning Goal:To leam about self-inductance from the example of a long solenoid.To explain self-inductance, it is helpful to consider the specific example of a long solervid, as shown in the figure. This solenoid has only one winding, and so the EMF induced by its changing current appoars across the solenoid itsel. This contrasts with mutual inductance, where this voltege appears across a second coil wound on the same cylincter as the lirst.Part ASuppose that the current in the solenoid is...
Question 3 A long solenoid with n turns per unit length of current I is wrapped around a cylindrical magnetic core of permeability μ μ0Hm The cylindrical core, extending along the z-axis, has radius α n turns per unit length, current I per turn Magnetic material of μ (a) If the solenoid is considered as infinite in length, it can be shown that the magnetic field, expressed in cylindrical coordinates, is: r> a Apply Ampere's law, using the rectangular path...
