The focus, focal length, and alignment of the beam can be easily varied by electromagnetic coils
, and a variety of beam patterns can be created--for example, zig-zag patterns for creating special area effects for surface heat treating.
A complete gradient insert consists of three orthogonal electromagnetic coils
. Each of the axes, both the axial Z gradient and the transverse X and Y gradients, is wound with wire or etched from a copper-clad sheet and potted together as a single mechanical unit.
All this is only the first step in the production of electromagnetic coils
Employing electromagnetic coils
to move the piston, and temperature probes in the measurement chamber, they are all accurate to [+ or -]1.0% and repeatable to 0.8% to help prevent correlation errors.
It uses a set of electromagnetic coils
that thump the underside of a leading edge metal skin, shedding the ice in a way similar to a pneumatic boot, but more reliable and with less maintenance.
embedded in the guideway walls govern propulsion.
Laser and electron beam heating are true beams that can be directed to the desired parts of the surface by mirrors or electromagnetic coils
. The surface can be rapidly scanned or an integrated shaped beam maybe used to control energy application.
The third, and largest, is an array of electromagnetic coils
The ABS system, as it is called, features electromagnetic coils
mounted around each cathode to supplement the magnets' degree of unbalance.
Adding to this, the demand for custom electromagnetic coils
that deliver optimum performance in transformers, electric motors, semiconductors, medical devices, as air coil inductors, etc.
