Ferrite magnets, as an important type of permanent magnet material, are widely used in various fields such as electronics, automotive, and industrial machinery due to their cost - effectiveness, good corrosion resistance, and relatively stable magnetic properties. Coercivity is a crucial parameter that characterizes the ability of a magnetic material to resist demagnetization. Accurately measuring the coercivity of ferrite magnets is essential for quality control, material research, and product design. This article will comprehensively introduce the methods for measuring the coercivity of ferrite magnets, including the principles, equipment, procedures, and factors affecting the measurement results.

I. Current Market Size and Overview
As of 2025, the global ferrite magnet market has witnessed significant growth and transformation. The market size has reached a substantial level, with various research reports providing different but complementary perspectives.

The rapid evolution of artificial intelligence (AI) has reshaped the hardware landscape, demanding servers capable of handling unprecedented computational loads. While rare-earth magnets like neodymium-iron-boron (NdFeB) dominate high-performance applications, ferrite magnets—composed of iron oxide and strontium/barium carbonate—are emerging as cost-effective, sustainable alternatives in AI server infrastructure. This analysis explores their applications across core components, thermal management, electromagnetic interference (EMI) shielding, and future innovations, highlighting their role in balancing performance, cost, and environmental impact.

The global permanent magnet market is dominated by two primary contenders: ferrite magnets and neodymium magnets. While both materials serve as indispensable components across industries, their distinct physical properties, cost structures, and application landscapes create a dynamic competitive environment. Ferrite magnets, known for their cost-effectiveness and thermal stability, dominate high-volume, low-power applications, whereas neodymium magnets, with their superior magnetic strength, excel in high-performance, space-constrained sectors. This analysis explores the multifaceted competitive relationship between these two magnet types, examining their strengths, weaknesses, market trends, and future trajectories.

Ferrite magnets, also known as ceramic magnets, have been a cornerstone of modern magnetic technology for decades. Composed primarily of iron oxide (Fe₂O₃) mixed with barium (Ba) or strontium (Sr) carbonates, these non-metallic, corrosion-resistant materials are renowned for their cost-effectiveness, thermal stability, and electrical insulation properties. Despite facing competition from rare-earth magnets like neodymium (NdFeB), ferrite magnets continue to dominate applications where durability and affordability outweigh the need for extreme magnetic strength. This analysis explores the future development trajectory of ferrite magnets, examining technological advancements, market trends, and emerging applications that will shape their role in a rapidly evolving global economy.

To determine if a ferrite magnet has failed, a comprehensive assessment involving multiple testing methods and criteria is essential. Below is a detailed guide on how to evaluate the failure of a ferrite magnet:
