摘要：The inductance value of air-core coils are adjusted using automated methods and inexpensive, noncomplicated apparatus. Adjusting tools are provided which displace coil turns in a linear motion with respect to the coil centerline. Specifically, the coil turns can be displaced by sliding perpendicularly to the coil centerline or by rotating a group of coils in order to modify the coil inductance. The adjusting tools used and the method of coil-turn displacement allow the automated method to reincrease the inductance of a coil in the event that displacement causes an over-decrease of inductance. 4494L
