Mutual Inductance And Inductance Calculations By Maxwell S from s2.studylib.net Therefore, the mutual inductance between two coils is said to be one henry if a current of 1a in coil 1 produces unit flux linkage in coil 2. Self and mutual inductance of linear conductors: Mutual inductance formula the formula of two coils is given as m= (μ0.μr. The unit of mutual inductance is also henry (h). When current i 1 flows through s 1, magnetic field, magnetic flux linked with s 2, this is the flux for a single turn though the area of s 2 is a 2, the flux will only generate in the area a 1 therefore for n 2 turns ….(1) where l is the length of the solenoids Mutually coupled opposing inductors connected in parallel in these formulas, the mutual inductance is determined as these two formulas are used in this calculator. The mutual inductance m can be defined as the proportionalitiy between the emf generated in coil 2 to the change in current in coil 1 which produced it. Mutual inductance formula two coils have a mutual inductance of 1h when an emf of 1v is induced in one coil by current changing at the rate of 1 a/s in the other coil.
Mutual inductance is the basic principle behind transformers, motors, generators, and other electrical components that interact with other magnetic fields.
The mutual inductance m can be defined as the proportionalitiy between the emf generated in coil 2 to the change in current in coil 1 which produced it. The value of k is always < 1. The mutual inductance m 21 of coil 2 with respect to coil 1 is the ratio of the flux through the n 2 turns of coil 2 produced by the magnetic field of the current in coil 1, divided by that current, that is, (14.2.1) m 21 = n 2 φ 21 i 1. Therefore, the mutual inductance between two coils is said to be one henry if a current of 1a in coil 1 produces unit flux linkage in coil 2. Mutual inductance formula two coils have a mutual inductance of 1h when an emf of 1v is induced in one coil by current changing at the rate of 1 a/s in the other coil. If the two inductors are aiding each other, the equivalent circuit is presented in fig. If i1 =1a and n 2 φ21 =1 wb turns, then m 21 =1h.
