High Temperature Can Make Magnets Lose Magnetism Quickly A magnet will lose some magnetism immediately when it encounters a high temperature that exceeds its own tolerance. How much high temperature does it need? This depends on the coercive force of the magnet, which is usually expressed by the letter after the magnet grade, such as [...]
Temperature Characteristics and Coefficient of Ferrite Magnets I saw some people on the Internet asking about the temperature characteristics and temperature coefficient of ferrite (the percentage of reversible change in magnetic properties when the temperature changes by 1°C is called the temperature coefficient of magnetic materials), today I will introduce you to this article. Ferrite [...]
4 Factors Causing Your Magnets to Get Weaker Get the most value from your investment by avoiding potential magnet-weakening forces. Here's how! Whether you are buying magnets for home, office, hobby, or industrial use, you surely want to protect your new purchase to ensure they last as long as possible and stay as strong as [...]
Magnets Are Still Effective Under Extreme Temperatures Want to know if your magnet will function properly under extreme temperatures? Read our blog or give us a call today to find out. Temperature has a variety of effects on magnetic materials Our customers are always curious about the effect temperature has on the magnets they need. [...]
What is Maximum Working Temperature of Permanent Magnet? When designing an application for permanent magnets it is essential to consider the temperature range that the magnet or magnets will be expected to work in. Yet, with so much information available (some of it incorrect) it is possible to associate the wrong magnetic property with the [...]
Types of Temperature Losses of Magnets (= loss of magnetisation due to high temperature) Depending on the temperature, we distinguish between three different types of losses: Reversible temperature loss Temperature area: just above the maximum working temperature The magnet is less magnetic as long as it is hot. Once it is cooled down, it regains [...]
Do magnets temperature affect magnetism in a magnet? Yes, temperature affects the strength of a magnet. Colder temperatures will permit the magnetic field strength to increase a bit and hotter temperatures will decrease it a bit. The effects can be demonstrated by a simple experiment with a bar magnet and a handful of carpet tacks. [...]
Temperatures of Different Magnets, Magnet's Temperatures Curie Temperature Ferrite : 460 ℃ - 480 ℃ Neodymium magnet: 320℃ - 380℃ SmCo magnet : 800℃ - 850℃ AlNiCo: 860℃ - 900℃ Temperatures of Different Magnets Maximum Operating Temperatures Ferrite : 300℃ Neodymium magnet: 80℃ - 200℃ SmCo5 : 200℃ - 250℃ Sm2Co17 : 300℃ [...]
