Consider the system shown in Figure1. The parameters of the system are as follows: (1) The relative permeability of the ferromagnetic core is: μr=80000 (2) The input voltage:Vin=10V (3) Number of turns in the coil:N=200 (4) Mean length of the flux lines travelling in the ferromagnetic material:lmean=50cm (5) Area of cross section of the coreAcore=5cm2 (6) The air gap length:g=20mm |
![]() The coil is connected to a variable resistance and the resistance is varied according to following sequence:
