What is the explanation of the BH curve?
The B-H curve or magnetisation curve is the graph plotted between magnetic flux density (B) and magnetising force (H). The B-H curve indicates the manner in which the magnetic flux density varies with the change in magnetising force. The following figure shows the general shape of B-H curve of a magnetic material.How do you demonstrate the BH curve using step by step method?
Step by step method
The specimen before being tested is demagnetized. The tapping switch S is set on tapping I and the switch S is closed. The throw of the galvanometer corresponding to this increase in flux density in the specimen, form zero to some value B, is observed.- So, the B-H curve for air will be a straight line passing through the origin. Therefore, the slope of B-H curve at any point is magnetic permeability.
