• What are magnetization curves explain?

  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.

• What is the magnetization curve of magnetic materials?

  The curve plotted between flux density B and magnetizing force H of a material is called magnetizing or B-H curve. The shape of curve is non-linear. This indicates that relative permeability (µr = B / ?H) of a material is not constant but it varies. B-H curves are very useful to analyze the magnetic circuit.

• What is the equation for the magnetization curve?

  Hence, mmf = NI = Hl At. For air, or any non-magnetic medium, the ratio of magnetic flux density to magnetising force is a constant, i.e. B H = a c o n s tan t . This constant is µ₀, the permeability of free space (or the magnetic space constant) and is equal to 4? × 10^-7 H/m.
• What is BH Curve? The plot of Hysteresis is known as a B-H curve, where B (The Material's Flux Density, measured in Teslas or Mega Gauss) is plotted on the vertical axis and H (The External Applied Magnetizing Force, measured in Amperes per meter) is plotted on the horizontal axis.
