Model No: SP-CUR-FER
It Consists of Electronic Circuit housed in a cabinet. One specimen sample of ferrite ring is supplied. This complete unit requires a C.R.O. to perform the experiment.
There are two windings on the specimen (primary and secondary).The primary is fed to low A.C. voltage (50 Hz). This produces a magnetic field H in the specimen. The voltage across R1 (resistance connected in series withthe primary) is proportional to the magnetic field. It is given to the horizontal input of the CRO. The A.C. magnetic field induces a voltage in the secondary coil. The voltage induced is proportional to dB/dT (B-flux density). This voltage is applied to a passive integrating circuit. The output of the integrator is proportional to B and fed to the vertical input of the CRO. As a result of the application of a voltage proportional to H to the Horizontal (input axis and avoltage proportional to B to the vertical (input) axis, the loop shown in fig. 2 is formed.
