toroidal core

Refer to Problem 3-11 and calculate the magnetizing inductance Lm if the mean path length equals 3.15 cm and the relative permeability µr = 2500.

Problem 3-11

A transformer is wound on a toroidal core. The primary winding is supplied with a square-wave voltage with a 250-V amplitude and B frequency of 100 kHz. Assuming a uniform flux density in the core, calculate the minimum number of primary winding turns required to keep the peak flux density in the core below 0.15 Wb/m2 if the core cross-sectional area is 0.635 cm2. Plot the voltage and flux density waveforms in steady state as functions of time.
