如何判断机械表是否受磁
1、磁场无处不在，防不胜防，原来带着好端端的手表，突然走时误差变大，首先就要猜测是否受磁了。机械手表里存在着很多钢质材料，比如大小钢轮、擒纵轮、齿轮的轴榫、轴承、螺丝和游丝，因此，手表非常容易被磁化。机械手表一旦磁化了，带来的影响首先是误差增大，严重的还会使手表停走。
2、当今社会生活中，电子产品无处不在，因此，在我们身边存在着或强或弱的磁场。各种类型的**磁铁在电器中也大量使用，典型的就是扬声器和马达，磁铁和直流磁场都能够磁化钢铁之类的“硬磁”材料。还有就是皮包上的磁扣，手表和信用卡都是**怕沾上磁的。

4、机械表受磁一般情况下是走快(严重的会停走)，如果游丝圈之间吸贴在一起，那手表就走的更快，大约能快2个小时/天左右。钢质零件**容易被磁化，包括擒纵轮和擒纵叉，还有游丝，磁力会影响和干扰摆轮的震荡周期。
5、那么，怎样判断机械表是否受磁呢?
(1)**简单的判断方法是用一个灵敏点指南针，平放。然后将手表近距离**的反复略过指南针的上方，这样的动作还需要把表多变化几个方位，再重复的进行。只要指南针的针动了，就说明表已经受磁了。
(2)机械表受磁了可以做退磁处理，退磁器的原理就是能产生一个交变磁场，将手表放入此磁场内，就退磁了如果是恒定磁场则会被磁化。退磁器有买或可以自制，一般专业表店都有退磁服务。
How to determine the magnetic mechanical watch
1, the magnetic field is everywhere, the original with good carry of watches, all of a sudden time error, the first is about to guess whether the magnetic. Manipulator table there are a lot of steel materials, such as the size of the steel wheel, the escapement wheel, gear shaft tenon, bearings, screws and balance spring, as a result, the watch is very easy to be magnetized. Mechanical watches once magnetization, the first is the error of the impact of the increase, serious still can make the watch had stopped.
2, in today's social life, electronic products everywhere, therefore, in our side there is a strong or weak magnetic field. Various types of permanent magnets in electric equipment is used in great quantities, is a typical speakers and motor, magnet magnetized and dc magnetic field can be "hard magnetic materials such as steel. As well as with magnetic clasp, watches, and credit card are the most afraid of with magnetic.
3, the magnetic field is everywhere, the original with good carry of watches, all of a sudden time error, the first is about to guess whether the magnetic. Manipulator table there are a lot of steel materials, such as the size of the steel wheel, the escapement wheel, gear shaft tenon, bearings, screws and balance spring, as a result, the watch is very easy to be magnetized. Mechanical watches once magnetization, the first is the error of the impact of the increase, serious still can make the watch had stopped.
4, mechanical watch by magnetic is generally going faster will stop walk (severe), if the balance spring circle between suction stick together, and then watch go faster, can quickly about 2 hours/days. Steel parts are most likely to be magnetized, including the escapement wheel and tackled longitudinal fork, and balance spring, magnetic will influence and interfere with the balance wheel oscillation cycle.
5, so, how to judge whether mechanical watch by magnetic?
(1) the simplest judgment method is to use a sensitive point of the compass, flat. Then watch close fast repeatedly over the top of the compass, which also need the watch change a few more orientation, repeat. As long as the compass needle to move that table has been affected by magnetic.
(2) mechanical watch by magnetic can do demagnetization, the principle of demagnetization device which is able to produce an alternating magnetic field, put a watch in the magnetic field, is the demagnetization if it is a constant magnetic field, it will be magnetized. Demagnetization device can have buy or self-control, generally watch shop have demagnetization and professional service.
