Electromagnetic force calculations for a conical coil
Metallurgical Transactions B, 1993Levitation melting devices used in the laboratory typically employ small conical coils with a reverse wound turn at the top. The magnetic field and the Lorentz forces on an electrically conducting sample, due to an alternating current flowing in a small conical coil, are studied by modeling it as a conical helix.

Implementation of optimized electromagnetic induction coils
SPIE Proceedings, 2014Electromagnetic induction (EMI) systems often employ separate transmit and receive coils that are placed in close proximity to one another. This placement is desirable for packaging reasons, but it makes achieving minimal mutual coupling between the two coils difficult.

The equivalence of electromagnetic coils for electron optics
Journal of Applied Physics, 1981The theoretical basis is discussed, and a stable, accurate, and efficient numerical procedure given for calculating the winding distribution that is needed on a designated target yoke so that the magnetic field it produces in a specified region of space is identical with that generated by a given primary yoke.

Fabrication of Excitation Coils for Electromagnetic Microactuators
2011A key component for electromagnetic micro devices is the coil. Exposing it to an electric current results in exciting a magnetic field. The three coils most commonly used in microactuators are the meander, the planar spiral, and the helical type. For fabricating these coils in thin-film technology a combination of photolithography (for creating a ...

Electromagnetic Optimization of Superconducting Dipole Coils
International Journal of Applied Electromagnetics and Mechanics, 1996Optimization techniques are applied in order to find geometrical solutions for coils used in superconducting accelerator dipole magnets. Relevant coil geometry parameterization and field computation methods are presented. Performances of some deterministic, stochastic and multistage optimization algorithms are discussed and preliminary results are ...
