Question
The B/H curve can be used to determine
- a. Iron Loss
- b. Eddy current loss
- c. Energy Loss
Solution
The B/H curve, also known as the magnetization curve or hysteresis curve, is a graphical representation of the magnetic properties of a material. It shows the relationship between magnetic field strength (H) and magnetic flux density (B).
a. Iron Loss: Iron loss, also known as core loss, is the power loss in an iron core caused by the magnetizing and demagnetizing of the core. The B/H curve can be used to determine iron loss by calculating the area inside the hysteresis loop. The larger the area, the higher the iron loss.
b. Eddy Current Loss: Eddy current loss is a form of power loss that occurs when a magnetic field induces a circulating flow of electrons, or "eddy currents," within a conductor. The B/H curve can be used to determine eddy current loss by looking at the slope of the descending part of the curve. The steeper the slope, the higher the eddy current loss.
c. Energy Loss: Energy loss in a magnetic material is the sum of the hysteresis loss, eddy current loss, and residual loss. The B/H curve can be used to determine energy loss by calculating the area inside the hysteresis loop (representing hysteresis loss) and considering the slope of the descending part of the curve (representing eddy current loss). The larger the area and the steeper the slope, the higher the energy loss.
