5.0 Theory of Operation

For the Model 7604 Magnetic Field Pickup Coil the voltage induced in the coil ei
is proportional to the area of the coil, the number of turns, the frequency, and the

average flux density within the area of the coil. Equation (1) gives this

relationship.

QUATION

(1)

For the Model 7604, the open-circuit coil-terminal induced voltage in microvolts

for a magnetic field strength B in picotesla is given in (2).

QUATION

(2)

The general equation for the conversion factor is given by (3) and (4), and

includes the effects of coil impedance and load impedance.
