The application of magnetic materials mainly falls into two categories: permanent magnetic materials and soft magnetic materials. They are widely used in energy, electronics, medical care, transportation and other fields, and different types of materials play a key role in specific scenarios. Details are as follows:

1)Traditional Industrial Fields‌

Power Transmission & Conversion‌: Soft magnetic materials (e.g., silicon steel sheets, ferrites) are employed in transformer cores and inductors for efficient energy transfer and conversion. Permanent magnets (hard magnetic materials) serve as critical components in industrial motors and generators.

‌Consumer Electronics & Appliances‌: Magnetic materials are integrated into speakers, refrigerator door seals, and sensors. Permanent ferrites and neodymium-iron-boron (NdFeB) magnets are extensively used in mobile phones and hard disk drives.

Mechanical Engineering‌: Electromagnetic cranes and automated control systems rely on soft magnetic materials for precise magnetic force regulation.

2) New Energy & Low-Carbon Sectors‌

Wind & Solar Energy Systems‌: NdFeB-based permanent magnet direct-drive wind turbines enhance energy conversion efficiency, while soft magnetic alloys stabilize power regulation in photovoltaic inverters.

New Energy Vehicles: ‌High-performance permanent magnets (e.g., NdFeB) and soft magnetic materials (e.g., amorphous alloys) are essential for drive motors, onboard charging modules, and battery management systems.

‌Energy-Efficient Devices‌: Inverter air conditioners and high-efficiency motors utilize magnetic materials to optimize energy consumption and reduce carbon emissions.

3) Advanced Manufacturing & Emerging Technologies‌

Industrial Automation & Robotics: ‌Servo motors and precision sensors depend on stable permanent magnets for accurate motion control.

‌Wireless Charging‌: ‌Soft ferrites and amorphous alloys improve energy transfer efficiency in electromagnetic induction coils.

Magnetic Storage & Information Processing‌

Ferrimagnetic materials enable data storage in hard disk drives and magneto-optical discs.

4) Defense & Specialized Applications‌

Military Equipment‌: ‌High-temperature-resistant rare-earth permanent magnets are critical for radar systems, missile guidance, and naval propulsion motors.

Medical Devices‌: ‌Superconducting magnets in MRI systems leverage specialized magnetic materials for high-resolution imaging.
