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.

A Primary Standard of Mutual Inductance
Metrologia, 1967The construction of a Campbell type calculable mutual inductor is described. The two primary helices, 29 cm in diameter, are wound on a fused quartz former and the 495 turn secondary winding is about 51 cm in diameter on a glass former. The accuracy of the calculated value, which is nominally 10 mH, is 2.0 in 106 with a 95% probability.

The significance of the sign of a mutual inductance
Mathematical Proceedings of the Cambridge Philosophical Society, 1932It is pointed out that there is some confusion concerning the meaning of the sign of a mutual inductance. The question is examined from first principles and it is shown that since the sign of a mutual inductance depends upon conventions as to sign of current directions, these, as well as the sign of the mutual inductance, must be given in order to ...

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.

Telephone Circuits with Zero Mutual Induction
Transactions of the American Institute of Electrical Engineers, 1919The paper deals with the reduction of inductive interference in telephone circuits. Various relative positions of two or more circuits, in which the mutual inductance is zero, and the mutual capacitance unbalance is approximately zero, are discussed. The most important case is that when the two wires of one circuit occupy opposite ends of one diagonal ...

Implant positioning system using mutual inductance
2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012Surgical placement of implantable medical devices (IMDs) has limited precision and post-implantation the device can move over time. Accurate knowledge of the position of IMDs allows better interpretation of data gathered by the devices and may allow wireless power to be focused on the IMD thereby increasing power transfer efficiency.

Quick on-chip self- and mutual-inductance screen
Proceedings IEEE 2000 First International Symposium on Quality Electronic Design (Cat. No. PR00525), 2002In this paper, based on simulations of top-level interconnects and CMOS devices of industrial 0.18 /spl mu/m technology, the rules to screen out those inductive interconnects requiring more accurate RLC considerations, and the victim wires potentially having significant inductive noises are developed.

Mutual inductance and transformers
2010This chapter will introduce the mutual inductance and transformer. A transformer is a device that is built based on the principle of mutual inductance and can be used to increase or decrease the voltage or current, and transfer electric energy from one circuit to another. It also can be used for impedance matching.

Proceedings of the American Institute of Electrical Engineers, 1915
Reasons are given for the selection of initial inductances as a means for calibrating current transformers, the most important of which is the wide use to which they may be put besides the calibration of current transformers. The design and manufacture of the apparatus is described, reasons being given for the choice of the form of the secondary coils ...
