from the book (e.g., how induction balance detectors work, motion vs. non-motion modes, ground balancing, discrimination, and search coil design).

Where is coil inductance (measured in microhenries, µH) and C is capacitance (picofarads, pF). A typical VLF coil might be 300 µH with a 0.022 µF capacitor, resonating at about 19 kHz. inside the metal detector pdf

: These eddy currents generate their own weak magnetic field. A second coil (or the transmitter coil itself in some designs) "listens" for this secondary field. from the book (e
