Mutual inductance of solenoid

(a) Calculate the mutual inductance M, assuming that all the flux from the solenoid passes through the outer coil The parallel capacitance, C p, is the equivalent capacitive effect between the turns of the coil, and the parallel resistance, R p, is the sum of all losses attributable to the core material The low-frequency inductance of single-turn rectangular loops made of. Thus, the self-inductance is 22 0 LN B n I µπRl Φ == (11.2.6) We see that L depends only on the geometrical factors (n, R and l) and is independent of the current I. Example 11.3 Self-Inductance of a Toroid Calculate the self-inductance of a toroid which consists of N turns and has a rectangular.Mu_Coil (ucoil) is the factor by which the presence of the rod magnifies the self. Mutual Inductance dt di M2 ε 1 =− • The induced emf opposes the magnetic flux change • The induced emf increases if the currents changes very fast • The induced emf depends on M, which depends only the geometry of the two coils and not the current. • For a few simple cases, we can calculate M, but usually it is just measured.
