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.

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.

Solid-projectile helical coil electromagnetic launcher
2007 16th IEEE International Pulsed Power Conference, 2007Summary form only given. Helical coil electromagnetic launchers (HCEML's) can operate at significantly lower currents and higher efficiency in comparison to conventional railgun and induction coilgun launchers. The HCEML's versatility is due, in part, to its large inductance gradient which is typically 2 to 3 orders of magnitude greater than a ...

Analysis of coil temperature rise in electromagnetic forming with coupled cooling method
International Journal of Applied Electromagnetics and Mechanics, 2020The long-life driving coil is the prerequisite for electromagnetic forming industrial application. Up to date, the temperature rise is one of the major factors that restrain its working life.

Review of Scientific Instruments, 1975
The second derivative of the axial magnetic flux density is found to vanish for an electromagnet composed of three circular coaxial coils if the spacing between adjacent coils is a, if each coil contains equal ampere turns, if the radii of the end coils are a, and if the radius of the center coil is ∼5a/4.

Design and testing of a coil-unit barrel for helical coil electromagnetic launcher
Review of Scientific Instruments, 2018A coil-unit barrel for a helical coil electromagnetic launcher is described. It provides better features of high structural strength and flexible adjustability. It is convenient to replace the damaged coil units and easy to adjust the number of turns in the stator coils due to the modular design.

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

Genetic Algorithms in Electromagnetism: The Helmholtz Coils
Journal of Applied Computer Science, 2006In this work, the modified genetic algorithm has been applied to solve the Helmholtz coil problem. The task of the algorithm was to determine the radius of the coils and the distance between them, which would assure that a priori assumed level of non-homogeneity of magnetic field is maintained.
