Its principle and some anti-theft devices are also different from sound magnetic and radio frequency. The following is a brief introduction to the use of the library security system.
The principle of electromagnetic wave used in the library security system is magnetic induction. Magnetic strips are installed on books that need anti-theft. Magnetic strips are generally hidden inside books, which are generally undetectable. Degaussing is performed on the degaussing machine when borrowing, and the door will not be activated to trigger an alarm. When returning the book, the manager only needs to magnetize the magnetizer to re-use it. There is also a permanent magnetic strip, which is not degaussing. This magnetic strip is installed on the library books that do not provide loans.
