Soft magnetic materials are those materials that are easily magnetised and demagnetised. They typically have intrinsic coercivity less than 1000 Am-1. They are used primarily to enhance and/or channel the flux produced by an electric current. Soft magnetic materials have been used widely in generators, transformers, and switching circuits. According to the new market research report “Global Soft Magnetic Materials Market Report 2023-2029”, published by QYResearch, the global Soft Magnetic Materials market size is projected to reach USD 5.43 billion by 2029, at a CAGR of 5.1% during the forecast period.
