20220406507 · 2022-12-22 ·

A solenoid device for generating or detecting electrical or magnetic fields includes at least two solenoids combined into a solenoid structure. A two level solenoid structure is formed by helically wrapping a long and bendable primary solenoid around a secondary core to create a secondary solenoid which includes the primary solenoid as a part. If the secondary solenoid is bendable and long enough, it can be helically wrapped around a tertiary core to form a tertiary solenoid which contains the primary solenoid and the secondary solenoid as parts. The upper level solenoid will generally contain a hollow core into which items or bodies to be treated with electrical or magnetic fields can be inserted for treatment. Further, items having inherent magnetic or electrical fields or properties can be inserted into the hollow core so the inherent fields can be detected.
