"I believe in limited government, and the 20th century has been the century of government. The data is uniform. The government has failed at every single task it has set out to do, with the exception of waging war."
- Bart Kosko

Hyperbolic Solenoid  
  Device that creates and manipulates magnetic fields.  

The cops pounced on a bulge in Methuen's pocket. The bulge was made by another wire contraption. Methuen shrugged. "My hyperbolic solenoid. Gives you a conical magnet field and enables you to manipulate ferrous objects at a distance. I picked the lock of the doors to the elevator with it."
From The Exalted, by L. Sprague de Camp.
Published by Astounding Science-Fiction in 1940
