known as a <strong>hysteresis curve<\/strong> or <strong>demagnetization curve<\/strong>, describes the relationship between:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>B (Magnetic Flux Density)<\/strong> \u2014 measured in Tesla (T) or Gauss (G)<\/li>\n\n\n\n<li><strong>H (Magnetic Field Strength)<\/strong> \u2014 measured in kA\/m or Oersted (Oe)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The curve illustrates how a magnetic material responds to an external magnetic field and how it retains magnetization after the field is removed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For permanent magnet engineers, the BH curve serves as a critical tool for evaluating:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Magnet strength<\/li>\n\n\n\n<li>Resistance to demagnetization<\/li>\n\n\n\n<li>Energy storage capability<\/li>\n\n\n\n<li>Temperature stability<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Key Parameters on a BH Curve<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Remanence (Br)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Remanence represents the magnetic flux density remaining after the external magnetic field is removed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Higher Br values generally indicate:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Stronger magnetic output<\/li>\n\n\n\n<li>Higher motor torque potential<\/li>\n\n\n\n<li>Better magnetic efficiency<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/hsmagnet.com\/magnetic-materials\/ndfeb-magnets\/\" type=\"page\" id=\"37\">NdFeB magnets<\/a> typically offer very high remanence compared to ferrite magnets.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Coercivity (Hc)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Coercivity measures a magnet\u2019s resistance to demagnetization.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A higher coercivity is critical for applications involving:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>High operating temperatures<\/li>\n\n\n\n<li>Reverse magnetic fields<\/li>\n\n\n\n<li>High-speed motors<\/li>\n\n\n\n<li>Compact magnetic circuits<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Applications such as EV traction motors often require high-coercivity NdFeB grades.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Intrinsic Coercivity (Hci)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Intrinsic coercivity represents the magnetic field required to fully demagnetize the material internally.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This parameter is especially important in:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>High-temperature environments<\/li>\n\n\n\n<li>Dynamic motor systems<\/li>\n\n\n\n<li>Harsh industrial applications<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Maximum Energy Product (BHmax)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The maximum energy product defines the maximum magnetic energy stored within the material.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><math xmlns=\"http:\/\/www.w3.org\/1998\/Math\/MathML\"><semantics><mrow><mi>B<\/mi><msub><mi>H<\/mi><mrow><mi>m<\/mi><mi>a<\/mi><mi>x<\/mi><\/mrow><\/msub><\/mrow><annotation encoding=\"application\/x-tex\">BH_{max}<\/annotation><\/semantics><\/math>BHmax\u200b<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Higher BHmax values allow engineers to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Reduce motor size<\/li>\n\n\n\n<li>Increase power density<\/li>\n\n\n\n<li>Improve efficiency<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">NdFeB magnets provide the highest commercially available BHmax among permanent magnet materials.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Understanding the Demagnetization Curve<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The second quadrant of the hysteresis loop is typically the most important for permanent magnet applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This region shows how the magnet behaves under opposing magnetic fields.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Key Engineering Insight<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A magnet operating too close to the \u201cknee point\u201d of the curve risks irreversible demagnetization.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is particularly important in:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Electric motors<\/li>\n\n\n\n<li>Generators<\/li>\n\n\n\n<li>High-current magnetic assemblies<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Engineers should design magnetic circuits with adequate safety margins to avoid entering unstable operating regions.<\/p>\n\n\n\n<figure class=\"wp-block-image

because engineers use room-temperature BH data for high-temperature applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Always evaluate BH curves at actual operating temperatures.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Over-Specifying Magnet Grades<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Higher-grade magnets increase cost significantly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In some cases, optimized magnetic circuit design delivers better ROI than simply selecting stronger magnets.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Operating Near the Knee Point<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Designing too close to the knee point increases demagnetization risk during overload conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Finite element analysis (FEA)
