What is Soft Magnetic Material?
The magnetic materials with low coercivity and high permeability (easy to magnetize and demagnetize) are classified as soft magnetic materials.
What is Hard Magnetic Material?
Once magnetized, the material that can maintain constant magnetism is called "hard magnetic material", also known as permanent magnetic material
Difference between Soft and Hard Magnetic Materials
Soft and Hard Magnetic Materials Examples
Soft magnetic materials mainly include metal soft magnetic materials, ferrite soft magnetic materials and other soft magnetic materials. The most widely used soft magnetic materials are ferrosilicon alloy (silicon steel sheet) and various soft magnetic ferrite.
The commonly used hard magnetic materials are divided into AlNiCo permanent magnet alloy, FeCrco permanent magnet alloy, permanent ferrite and rare earth permanent magnet materials
Hysteresis Loop for Soft and Hard Magnetic Materials
The hysteresis loop reflects the magnetization of ferromagnet. The hysteresis loop is a closed curve of the relationship between the magnetic induction intensity and the magnetic field intensity produced by ferromagnetic materials under the action of an external alternating magnetic field.
Hard magnetic materials refer to ferromagnetic materials with large hysteresis loops, while soft magnetic materials have small area surrounded by hysteresis loops.
