Hysteresis Loss and Eddy Current Loss

Hysteresis Loss and Eddy Current Loss: When a magnetic material undergoes cyclic magnetization, two kinds of power losses occur in it Hysteresis Loss and Eddy Current Loss which together are known as core-loss. The core-loss is important in determining heating, temperature rise, rating and efficiency of transformers, machines and other ac run magnetic devices. Hysteresis […]

Magnetic Circuit Calculations

Magnetic Circuit Calculations: Normally magnetic circuit calculations involve two types of problems. In the first type of problem it is required to determine the excitation (mmf) needed to establish a desired flux or flux density at a given point in a magnetic circuit. This is the normal case in designing electromechanical devices and is a […]
