If there is more than one current-carrying conductor other than of the same phase, placed adjacent to each other, so that the electric field produced by one can link the other, mutual induction will take place. The magnitude of this will depend upon the amount of current and the spacing between the two. This tends to further distort the selfresistance of the conductor over and above the distortion already caused by the skin effect current distribution... 

The enclosure is constructed of non-magnetic material, generally aluminium, in view of its low cost and weight as compared to copper The nonmagnetic material eliminates hysteresis and eddy current losses in the enclosure, as i result of mutual induction,... 

The values in Fig. 23-5 have to be corrected in the case of differing resistivity values because of the dependence of mutual inductance on the soil resistivity. This is achieved by substituting an equivalent distance, a instead of the real distance, a, giving ...

Average distance, a, with equivalent counter-inductivity for an oblique approach with distances <3, and <32 at the end of the close proximity (<3, < <32)-(a)/= 50 Hz and p = 50 m, (b)/= 16% Hz and p = 30 m.

Examples of such situations are very numerous perhaps the best known example is the transition of the performance of an electronic circuit from regenerative amplification to the generation of oscillations. The parameter A in this case is the coefficient of mutual inductance between the anode and the grid circuits. As long as A < A0, the circuit functions as amplifier whose coefficient of amplification gradually... 

Gopala Rao and Venkateswara Rao found that the oxidation of indigo to isatin by chromic acid is accelerated by the presence of oxalic acid, and at the same time the extent of the oxidation of oxalic acid by chromic acid is increased. This observation is an example of mutual induction. 

The scaling factor Sj can take any value between 0 and 1 and is applied to site j. The superscripts p and m indicate permanent and mutual induction, respectively. Equation (9-19) can be solved iteratively using similar procedures to those used to solve Eq. (9-3). The formal permanent moments can be calculated by subtracting induced moments from moments from ab initio calculations. For any conformation of a given compound the atomic multipoles can be determined from Distributed Multipole Analysis (DMA) [51].

For this type of thermometry a mutual inductance meter of high sensitivity (10 9 H) is needed. 

Deviations from the l/T dependence are generally observed these are due to magnetic parasitic contributions (see example of Fig. 9.16 where M0 is the mutual inductance of... 

The SI unit (symbolized by H) for both self-inductance and mutual inductance. One henry represents the inductance produced when an induced electromotive force of one volt is generated as the inducing current is altered at a rate of one ampere per second. (Hence, one henry is equivalent to one volt-second per ampere or one weber per ampere). See Magnetic Susceptibility Permeability...

Mutual inductance requires two parts the inductors (L) and the coupling between the inductors (K). We will illustrate the use of the coupling part K with two circuits. The first circuit will have three inductors with unequal coupling. The second circuit will have four inductors with equal coupling. Wire the circuit shown below. The dots on the inductors are critical since they indicate the polarity of the mutual coupling. Make sure the dots on your schematic agree with the ones on the schematic shown. 

Mutual inductance requires two parts the inductors (L) and the coupling (K). 

The distance dependence of 1/r6 for the attractive potential is characteristic of the interaction between dipoles. This is because the attractive dispersion forces result from the mutual induction of electrostatic dipoles. Although a nonpolar molecule has no net dipole averaged over a period of time, at any one instant there will be dipoles due to the local fluctuations of electron density. Because the energies depend on the induction of a dipole, polarizability is an important factor in the strength of the interaction between any two atoms. 

The two secondary windings are connected in series opposition so that the output voltage is the difference of the voltages in the secondary windings (i.e. V0 = V, - V2, Vt > V2). A ferromagnetic core moves inside the primary coil and thus varies the mutual inductance between the primary and secondary coils which in turn varies the secondary voltages. The displacement of the pressure sensor (capsule, bellows or... 

Clearly, such interference can be reduced by increasing the distance between the source and the measurement circuit—mutual inductance and capacitance both being inversely proportional to the distance. Inductive coupling can also be much reduced by the use of twisted pair cable (Fig. 6.65). If adjacent loops in the circuit have the same area (e.g. loops 1 and 2) and are coupled with the same magnetic field, then the induced voltages between points A and B and between B and C will cancel each other out, and this will be repeated along the whole section of twisted pairs.
