#### (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.

**Inductance**Of A Coil. 00 ms, inducing a 9 [2] It is customary to use the symbol The self-

**inductance**L of a coil of n turns (

**solenoid**or toroid) is given by where Φ is the flux in the coil and I is the current

**Mutual inductance**M12 is the link that exists between the flux circulating in a coil 1 generated by the circulation of a current i2 in a coil 2 One important point. At. 2:18. he states that Total flux=Mi. In prior videos he has stated that Total flux =Li/N. Since L and M both represent

**inductance**, what happened to "N" in the Total Flux=Mi equation.
