Magnetic materials are used in various branches of modern industry to ensure the durable and uninterrupted operation of many devices and systems. However, under different operating conditions, not all magnetic materials are equally effective. The two main types of magnetic alloys — hard magnetic and soft magnetic — differ significantly in their properties and applications.
Magnetic-hard materials, also known as permanent magnetic materials, are characterized by their ability to maintain permanent magnetization after interacting with a magnetic field. They have a high coercive force and low magnetic permeability. These materials are usually difficult to demagnetize and have high hysteresis losses due to the large area of the hysteresis loop.
Hard magnetic alloys are widely used to create permanent magnets that are used in various industries, including instrument making, manufacturing medical equipment, manufacturing complex electrical systems, and much more.
Soft magnetic materials they are easily magnetized under the influence of an external electric field and demagnetized after removal from it. They are characterized by low coercive force and high magnetic permeability. They have a small hysteresis loop area, thereby reducing hysteresis losses. As a rule, soft magnetic alloys have high resistivity, which reduces eddy current losses that occur in these materials.
Soft magnetic materials are best suited for creating magnetic circuits in electrical machines and other devices that require the transfer of magnetic flux.
The differences between magnetic-hard and magnetic-soft materials are determined by their characteristics of magnetization, coercive force and magnetic permeability. Hard magnetic alloys retain their permanent magnetization and are widely used to create permanent magnets, while soft magnetic materials are easily magnetized and demagnetized, which makes them an ideal choice for magnetic circuits in electrical devices and electrical equipment.
