moreover, in the process of the development of today's social life, more and more electronic procts appear around us. Therefore, the magnetic field is around us, there is only the difference between the strength of the magnetic field. Various types of permanent magnets are also widely used in electrical appliances, such as loudspeakers and motors. Magnets and DC magnetic fields can magnetize "hard magnetic" materials such as steel. There is also the magnetic buckle on the leather bag. Watches and credit cards are most afraid of getting magnetic. A mechanical watch is usually fast when it is magnetized (it will stop if it is seriously magnetized). If the hairspring rings are glued together, the watch will go faster, about 2 hours / day faster. Steel parts are most easily magnetized, including escapement wheels and escapement forks
a simple way to judge is to use a sensitive point compass and lay it flat. Then the watch quickly and repeatedly over the top of the compass, such action also need to change a few more directions of the watch, and then repeat. As long as the compass needle moves, it means that the watch has been magnetized. Mechanical watch can be demagnetized when it is magnetized. The principle of demagnetizer is to proce an alternating magnetic field. If the watch is put into this magnetic field, it will be demagnetized. If it is a constant magnetic field, it will be magnetized. Demagnetizer can be bought or self-made, general professional watch shop has demagnetization service. Moreover, in later daily life, we must pay attention not to put the watch next to or near the electrical appliances (such as audio, refrigerator, computer, etc.) that generate magnetic field, or magnetic objects (such as magnets, mobile phones).
method 1: if there is water inflow in the watch case, a granular material called silica gel can be put into a closed container together with the watch that has accumulated water. After a few hours, take out the watch and the water will disappear. This method is simple and economical, without any damage to the accuracy and life of the meter. The silica gel that has absorbed water for many times can be dried at 120 ℃ for several hours. The water absorption capacity is renewable and can be used repeatedly
method 2: if the water is not serious, but there is a layer of fog in the surface glass, then wrap the surface tightly with several layers of toilet paper or absorbent flannelette, and bake it at 15cm away from the 40W light bulb for about 30 minutes to eliminate the water vapor. Do not bake the cover close to the fire, so as not to deform the cover. It can also be worn on the wrist with the watch cover facing inside and the bottom shell facing out, and the moisture can be eliminated after two hours. If the water is serious, it's better to send it to the meter shop to wipe oil immediately to remove the moisture of the movement, so as to avoid parts rusting
it should be noted that if the electronic meter is flooded, the battery should be removed in time. Whether it is a mechanical meter or an electronic meter, if the water is serious, it should be sent for repair in time.
There are many kinds of medical insurance in the United States, which often confuse the first-time applicants. There are student medical insurance for students and unlimited private insurance for the rich. American medical insurance system
Atlas of American medical insurance system
the coverage of the federal government's medical insurance is also very broad, including "medical care" insurance for the elderly and the disabled over the age of 65, and "medical care for the poor" plan for low-income families
in the United States, rich people can have more than one private doctor, and the cost of seeing a doctor anywhere in the world is "reimbursement" on the condition that they pay an expensive monthly insurance premium. The poor can only look for those medical insurance institutions with lower insurance premiums and go to designated hospitals for treatment. People who can't make ends meet may not take part in any medical insurance. Once they have to see a doctor, they can queue up in public hospitals and fill in lengthy and tedious declaration forms to get a free prescription
the medical savings account is another new type of insurance that has just been tried out in the United States last year. As soon as it was launched, it was welcomed by many low - and middle-income people
participants in the scheme can set up a special personal account in the bank, which only deposits 138 US dollars a month, and can set up a self payment scheme of less than 2250 US dollars. The family insurance fee is 431 US dollars. If the total medical expenses of the whole family exceed 4500 US dollars, the insurance company will bear it. The expenses of seeing a general dentist, vision correction, and psychologist can also be reimbursed. At present, in general medical insurance, the indivial's monthly insurance premium is at least $200. In addition, ordinary medical insurance, even if you don't see a doctor or go to hospital, you can't get the premium back
however, the characteristic of medical savings account is that each year, the indivial only needs to put 65% of the out of pocket amount, and the family only needs to put 75% of the out of pocket amount into the bank, which needs to be dected from this account only when the doctor and the patient are in hospital. When the patient is not in hospital, the money is naturally put in the bank like a current deposit, which not only has interest, but also does not need to pay tax
