ABSTRACT

The electromagnetic distribution around the solenoidal ferrite core was shown in a shape of symmetric and decreased as a function of distance by an exponential function and the electrical characteristic of the experimental solenoidal ferrite that considered unloaded primary coil, have shown a good agreement compared to the commercially used in the market. As a result of simulation, magnetic flux density value in middle of lamp bulb is 2.091x10-[Wb/m2].
