INDUCTION COILS: VOLTAGE VERSUS CURRENT OUTPUT
P. Kašpar, P. Ripka
Abstract:
The stationary air - cored induction coils are often used for the measurement of AC magnetic fields in the air. The voltage induced in classical voltage output coil is proportional to the time rate of change of the magnetic flux and to the turn – cross-section product N A. Increasing of the number of turns N causes increasing of the parasitic capacitance. Parasitic capacitance with the inductance of the coil creates resonant circuit and thereby decrease the maximum measured frequency. In the case of the short-circuited coil the frequency range of the sensor is essentially expanded. Measurements performed on two types of induction coils using both modes are described in the present paper.
