Abstract :
Two types of relaxation polarisation are combined to analyse the frequency spectrum of the complex permittivity of MnZn ferrite. The dielectric loss of the toroid core has been calculated based on this polarisation model. Results show that the dielectric loss accounts for 25% of the total loss in the megahertz region
