Mutual Inductance and Transformers
2021A common transformer has a pair of coils: the primary coil and the secondary coil. A transformer operates on the principals of “electromagnetic induction”, in the form of mutual induction. A transformer is able to either increase or decrease the voltage and current levels of their supply, without modifying its frequency and the amount of electrical ...

A STANDARD OF MUTUAL INDUCTANCE
Canadian Journal of Physics, 1955A primary standard of mutual inductance of the Campbell type has been constructed by the National Research Council to serve as an ultimate standard of reference for electrical quantities in Canada. The electrical value is computed from its measured physical dimensions. A detailed description is warranted in view of its national importance.

International Comparison of Standards of Mutual Inductance
Metrologia, 1968Abstract : The National Research Council (Canada) and the National Physical Laboratory (United Kingdom) have each obtained the units of reactance and resistance from the metre and second by the use of similar Campbell standards of mutual inductance. A direct comparison of the units of inductance derived in the two laboratories has been made, using a ...

Inductance and mutual inductance
1996The inductor is one of the basic building blocks upon which electrical and electronic circuits are founded, and form a springboard to important branches of the subject. The reader will gain confidence in dealing with problems relating to inductive circuits as he/she reads through this chapter.

Mutual inductance extraction and the dipole approximation
Proceedings of the 2004 international symposium on Physical design, 2004The present work is centered in the controversy between two approaches to inductance extraction: loop vs. partial treatments for IC applications. We advocate for the first one, justifying this claim in terms of representing more realistically the physical situation, as well as having better sparseness properties.

Nature, 1948
WHEN heat is dissipated from a hot body immersed in a fluid, the flow of heat is accompanied by a mechanical circulation of the fluid in the system of natural convection currents. The stored kinetic energy bestows on the heat current a property which has been termed ‘thermal ‘inductance, and curves I have obtained1 for the thermal transients consequent

Optimal coils with zero mutual inductance for electromagnetic induction systems
2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013Electromagnetic induction (EMI) systems often use separate transmit and receive coils. In these systems, it is desirable for the transmit and receive coils to have both minimal mutual coupling and a maximum field product, thus maximizing the detection depth.

Calibrating Standards of Mutual Inductance
2005 IEEE Instrumentationand Measurement Technology Conference Proceedings, 2006As the final stage of development of a new system for impedance calibrations, a facility for calibrating standards of mutual inductance has been realized. Being based on the three-voltmeter method, this facility makes it possible to calibrate 1 mH to 100 mH standards at frequencies up to 5 kHz with uncertainties of the order of 0.01 %.

Interphase Mutual Inductance in Polyphase Inductive Power Transfer Systems
IEEE Transactions on Industrial Electronics, 2009Roadway powered electric vehicles with minimal or no onboard energy storage have been proposed for many years, but the concept has only recently become feasible via three-phase inductive power transfer (IPT) systems. A wide zone can be created over which power transfer is relatively constant.
