Artificial magnetism
The magnetic field generated by natural magnets is too weak and does not affect the operation of the watch. However, the artificial magnetic field is different. In the early part of the 0.19 century, when scientists discovered how large currents were generated, strong magnetic fields also produced with electromagnetic induction. This important physical phenomenon was discovered by Faraday in 1831, and began the development of practical applications of current, such as motors, generators, telegraphs, telephones, and radios. In 1872, Siemens built the first truly efficient motor, and in the next 30 years, it can be seen in a small workshop with electricity.
By the end of the 19th century, motors began to be widely used, and the problem of magnetization of pocket watches became more and more common. The first "victims" of artificial magnetism were the hired workers in the electric power plant. Early generators created strong magnetic fields that would have a negative impact on watches worn in the workplace.
The solution to this problem is a device consisting of a horseshoe magnet that relies on a crank to rotate. At half a turn, the magnetic pole at any known point changes direction. It can be demagnetized by selectively moving the magnetizer to the device and then removing it. (Until today, we are still using the same principle except that the horseshoe magnet is replaced by a high-magnification coil that is connected to an alternating current.)
