Depending on power consumption and duty cycles, cooling may be unnecessary, or provided/supplemented by forced air.Square or rectangular wire options enable reduced power requirements over round wire. • Extremely high winding precision • Highest field accuracy with lowest transverse field • Highest fill and packing factor, yielding highest field to weight ratio • Economical to build in larger quantities • Most compact weight and space-saving configuration • Most flexible configuration in shape and size • “Sculptable” for slots and holes • Vastly improved heat dissipation A super-thin insulation layer between foil windings allows fill factors (compactness) unavailable from wire or hollow-tube windings. Foil also spreads current more evenly throughout each coil. Unlike wire wound, foil coils can be cut or sculpted to accommodate special mounting or access needs. The current path is largely undisturbed, and the impact on the magnetic field is minimal.

Foil construction has high thermal conductance, enabling cooling to occur in layers between windings. • Best for “brute strength” applications requiring high power (20 kGauss and greater) • Coaxial coolant path in direct contact with entire coil length • Highest thermal conductance delivers maximum heat dissipation • Extremely malleable into complex or unusual shapes Liquid coolant flows through the entire coil length inside the hollow tube centers. This allows greater winding heat transfer than any other construction method, enabling the highest field strengths with extremely low temperature rise. Non-conductive tubing (plastic shown) carries coolant without impacting the magnetic field pattern. Stangenes design routes cooling liquid in parallel, despite the necessary series path for coil current. Each coil set receives fresh incoming coolant at the same temperature.
Positive isolation of turns eliminates shorting, allowing low AC losses. Extreme flexibility and malleability enables electromagnets of nearly any shape, including racetrack, thin pancake, open yoke and much more.
The fundamental equations of classical macroscopic electrodynamics that describe electromagnetic phenomena in any medium. The equations were formulated by J. Maxwell in the 1860’s on the basis of a generalization of the empirical laws of electric and magnetic phenomena. By using these laws as a basis and developing M. Faraday’s productive idea that the interactions between electrically charged bodies take place through an electromagnetic field, Maxwell created the theory of electromagnetic processes, which is expressed mathematically by Maxwell’s equations. The present form of the equations was given by the German physicist H.
Hertz and the British physicist O. Maxwell’s equations relate the quantities that characterize an electromagnetic field to its sources, that is, to the spatial distribution of electric charges and currents. In a vacuum, the electromagnetic field is characterized by two vector quantities that are dependent on spatial coordinates and on time—the electric field intensity E and magnetic induction B.
