Optimization of planar coils for electromagnetic induction systems
2014 IEEE Geoscience and Remote Sensing Symposium, 2014Continuous-wave electromagnetic induction systems used for subsurface sensing often employ separate transmit and receive coils. In these systems, it is desirable to have zero mutual coupling between the transmit and receive coils and for the coils to have maximum sensitivity at a specific location.

An adjusted dipole model for rectangular electromagnetic coils
2016 IEEE International Conference on Information and Automation (ICIA), 2016Magnetic actuation is an efficient way for remote wireless control of micro-robots. One key factor for efficient actuation is an accurate mapping of the magnetic field components and the field gradients that generated by the magnetic sources. Usually, magnetic dipole model or interpolation method is used to estimate the magnetic field.

Electromagnetic actuator for voice coil
The Journal of the Acoustical Society of America, 1979An electromagnetic actuator for linear driving of movable heads of a magnetic disc unit in an information processing system. A plurality of slits or plates are provided with a magnetic pole inscribed directly on the internal surface of a permanent magnet, and increase magnetic reluctance of the magnetic path and reduce inductance of a moving coil, thus

A novel electric design for electromagnetic stimulation-the Slinky coil
IEEE Transactions on Biomedical Engineering, 1995A novel coil design for inductive electromagnetic stimulation of neural cells has been simulated and experimentally tested. This coil improves the focal effect of a magnetic stimulator, and it reduces its inductance, hence the efficiency of the system is improved. The basic structure of the device is derived from the popular "Slinky" toy.

Thermal analysis of electromagnetic levitation coil
2016 17th International Scientific Conference on Electric Power Engineering (EPE), 2016This paper presents analytical and numerical thermal analysis of three different toroidal coils levitated on an aluminum plate. The analytical method consists of a network of thermal resistances that make it possible to estimate the average temperature of the coils.

Electromagnetic force analysis of a driving coil
2012 16th International Symposium on Electromagnetic Launch Technology, 2012Electromagnetic force (EMF) analysis and configuration design of a driving coil is quite important for a coil launcher. Lots of efforts have been focused on armature and control system to improve efficiency or interior ballistic characteristic. By contrast, EMF performance of a driving coil is rarely researched.

A Versatile Laboratory Electromagnet With HTS Coils
IEEE Transactions on Appiled Superconductivity, 2004We report the development of a laboratory electromagnet utilizing high temperature superconducting (HTS) coils which is designed to generate fields in excess of 3 Tesla, but with power consumption and size significantly below that possible with copper-wound coils for an equivalent useful field volume.

Optimized coils for electromagnetic induction systems
SPIE Proceedings, 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 minimal mutual coupling and a maximum eld product, thus maximizing the detection depth. We demonstrate that a pair of spiral coils can be optimized to achieve these desired properties.

Optimized electromagnetic coil design theory
Proceedings IEEE Southeastcon '92, 2003The authors review the general theory of electromagnetic coil design, the starting point for which is the Biot-Savart equation, which expresses the relationship between current distribution and the resultant static magnetic field. They introduce a reformalization of the Biot-Savar equation which provides for the general design of electromagnetic coils ...
