Yes.<\/strong> Heating a permanent magnet usually reduces its magnetic output while it is hot.

Intrinsic coercivity (Hcj), geometry, magnetization direction, air gap, steel return path, reverse-field exposure and the required hot-state output all affect the decision.<\/p>\n<\/div>\n<div class=\"toc\">\n<strong>On this page<\/strong>\n<ol>\n<li><a href=\"#why-heat-weakens-magnets\">Why heat weakens magnets<\/a><\/li>\n<li><a href=\"#br-hcj-temperature\">How Br and Hcj change with temperature<\/a><\/li>\n<li><a href=\"#reversible-irreversible-curie\">Reversible loss vs irreversible loss vs Curie temperature<\/a><\/li>\n<li><a href=\"#how-hot-is-too-hot\">How hot is too hot for neodymium magnets?<\/a><\/li><li><a href=\"#temperature-selection-guide\">How to choose NdFeB for higher temperature<\/a><\/li>\n<li><a href=\"#cold-magnets\">Does cold make magnets stronger?<\/a><\/li>\n<li><a href=\"#geometry-circuit-temperature\">Why geometry and the magnetic circuit change temperature capability<\/a><\/li>\n<li><a href=\"#gauss-pull-force-temperature\">Why Gauss or pull force alone can mislead you<\/a><\/li>\n<li><a href=\"#material-comparison\">NdFeB vs SmCo vs ferrite vs Alnico<\/a><\/li>\n<li><a href=\"#verify-thermal-performance\">How to verify thermal performance<\/a><\/li><li><a href=\"#simulation-validation\">When to use simulation or thermal validation<\/a><\/li>\n<li><a href=\"#temperature-selection\">What to send for a temperature-critical magnet<\/a><\/li>\n<li><a href=\"#temperature-faq\">FAQ<\/a><\/li>\n<\/ol>\n<\/div>\n<h2 id=\"why-heat-weakens-magnets\">Why Does Heat Weaken Magnets?<\/h2>\n<p>Heat changes the magnetic properties of a permanent-magnet material. In a simplified picture, rising temperature increases thermal agitation and makes it harder for the material to maintain the same magnetic order. The result is usually lower magnetic output as temperature rises.<\/p><figure class=\"content-visual\"><img loading=\"lazy\" alt=\"Neodymium magnets in a realistic industrial environment near a heat-generating machine\" decoding=\"async\" height=\"900\" loading=\"lazy\" src=\"https:\/\/osenc.com\/wp-content\/uploads\/2026\/09\/ndfeb-magnets-industrial-heat-environment-20260910-2238.webp\" width=\"1200\"\/><figcaption>In real equipment, the magnet can run hotter than the surrounding air because heat is conducted from motors, housings, coils or nearby metal components.<\/figcaption><\/figure>\n<p>That answer is correct, but it is still too crude for selecting a neodymium magnet. A magnet can become weaker while hot and then recover after cooling, or it can lose part of its magnetization permanently. The difference depends on where the magnet operates on its demagnetization curve at the highest temperature.<\/p>\n<div class=\"key-point\">\n<strong>The engineering question is not simply \u201cWill heat weaken the magnet?\u201d<\/strong>\n<p>It is: \u201cAt the hottest real operating condition, will the magnet still have enough flux and enough coercivity margin to stay away from irreversible demagnetization?\u201d<\/p>\n<\/div>\n<h2 id=\"br-hcj-temperature\">How Do Br and Hcj Change With Temperature?<\/h2>\n<h3 id=\"what-happens-to-br\">What Happens to Br?<\/h3><p>When buyers say \u201cmagnet strength,\u201d they often mix several different properties.

That is why a magnet can still show useful magnetic output while its safety margin against irreversible loss has already become much smaller.<\/p><p class=\"source-inline\" id=\"arnold-temperature-source\">Source for representative NdFeB temperature-coefficient behavior: <a href=\"https:\/\/www.arnoldmagnetics.com\/wp-content\/uploads\/2017\/10\/TN_0303_rev_150715.pdf\" rel=\"nofollow noopener\" target=\"_blank\">Arnold Magnetic Technologies technical note<\/a>.<\/p>\n<div class=\"table-scroll\">\n<table>\n<thead>\n<tr>\n<th>Variable<\/th>\n<th>Typical effect of rising temperature in NdFeB<\/th>\n<th>Why it matters<\/th>\n<th>Procurement \/ design action<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Br<\/td>\n<td>Decreases<\/td>\n<td>Hot-state flux and field are lower than at room temperature.<\/td>\n<td>Define the minimum acceptable performance at the actual operating temperature.<\/td>\n<\/tr>\n<tr>\n<td>Hcj<\/td>\n<td>Decreases, often more strongly than Br<\/td>\n<td>Resistance to irreversible demagnetization becomes weaker.<\/td>\n<td>Check the hot demagnetization curve and operating point instead of relying only on room-temperature grade.<\/td>\n<\/tr>\n<tr>\n<td>BHmax<\/td>\n<td>Changes with the material curve<\/td>\n<td>Room-temperature energy product does not describe hot-state system performance.<\/td>\n<td>Do not assume a higher N-number automatically gives better thermal performance.<\/td>\n<\/tr>\n<tr>\n<td>Operating point<\/td>\n<td>Moves as the curve changes<\/td>\n<td>A design with weak permeance-coefficient margin can cross the knee at elevated temperature.<\/td>\n<td>Review geometry, air gap, steel return path and any opposing magnetic field.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>A representative sintered NdFeB material can have a reversible Br temperature coefficient around <strong>-0.11% per \u00b0C<\/strong>.

Reversible temperature loss<\/h3>\n<p>When the magnet stays within a suitable operating region, magnetic output falls as temperature rises and largely returns when the magnet cools. This is the behavior described by a reversible temperature coefficient.<\/p>\n<h3>2. Irreversible demagnetization<\/h3>\n<p>If the hot operating point moves beyond the knee of the demagnetization curve, part of the magnetic loss remains after the magnet cools. The magnet may still work, but its room-temperature flux can be lower than before the heat exposure.<\/p>\n<p>Some irreversible loss can be recoverable by remagnetization if the material has not suffered permanent structural damage. That does not fix a bad design. If the same magnet is returned to the same thermal and magnetic conditions, the loss can happen again.<\/p>\n<h3>3. Curie temperature<\/h3>\n<p>The Curie temperature is the much higher material transition where normal long-range magnetic order collapses. A representative sintered NdFeB material has a Curie temperature around <strong>310\u00b0C<\/strong>.

But those published numbers are not universal guarantees.<\/p>\n<p>Even within the same nominal grade family, the allowable temperature can change with magnet shape and operating point.
