One, electro-acoustic devices: cell phones, televisions, stereos, headphones and all other sound-producing devices, are realized by the magnet as a permanent external magnetic field with the coil, diaphragm vibration.
Two, electronic devices: cell phones, tablet computers, such as dormant holsters.
Three, bags and holsters and many other items use magnets to adsorption fixed.
Four, the medical field: medical examination of the most commonly used nuclear magnetic **** vibration. Is the use of the body's own magnetic field and the instrument itself carries magnetic material, interaction, the formation of detection of imaging, to help people see the cause of the lesion. Similarly in other medical treatment, there are many traces of the application of magnets, such as acupuncture and magnetic therapy, magnetic sensory detector.
Fifth, daily life in the field of electrical appliances, the application of magnets is even more extensive. Induction cookers, microwave ovens, and other electrical appliances, are a large number of magnets, so that they can play a better role in environmental protection and safety.
Expanded information:
In the traditional industrial field, due to the generation of electricity to be used to generators, power transmission to be used to transformers, televisions to be used to speakers, electric machines to be used to Electric motors telephone radios, etc., too many too many instruments and meters have to use the magnetic steel coil structure, so it can be said that, if there is no magnetic material, electrification becomes impossible.
Magnets in the medical field is the most important application of nuclear magnetic **** vibration, the use of this nuclear magnetic **** vibration imaging technology can diagnose abnormal tissues of the human body, the judgment of disease. In addition, the magnetic field and the human body meridian interaction can also realize the magnetic therapy, there are magnetic therapy pillow, magnetic therapy belt and other products appear.
