For what purposes are ferromagnetic materials used?
| November 14, 2020 | Education
The use of ferromagnetic materials is mainly based on the fact that: 1) they amplify the magnetic field many times over; 2) they remain magnetized when the external magnetic field is turned off.
The first property determines their use for energy saving. Due to the second property, ferromagnets are used in electrical measuring instruments, sound recording devices, and so on.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
