What are the applications of magnets in life about magnets in life applications

1, electro-acoustic devices: cell phones, televisions, stereos, headphones and so on all the audible speakers, these speakers are converted into electrical signals into acoustic signals of a device. Mainly consists of fixed permanent magnets, coils and conical paper cone. When the sound in the form of audio current through the coil in the speaker, the magnetic field produced by the magnet on the speaker will produce force on the coil, the coil will be due to changes in the strength of the current to produce a different frequency of vibration, which in turn drives the paper cone to send out a different frequency and strength of the sound. The paper cone spreads the vibrations through the air, and that's what produces the sound we hear.

2, electronic devices: cell phones, tablet computers hibernation holster.

3, bags and holsters and many other items use magnets to attract and hold.

4, the medical field: the most commonly used in the medical examination of 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 manifestation, help people see the cause of the lesion. Similarly in other medical treatment modalities, there are many traces of the application of magnets, such as acupuncture and magnetic therapy, magnetic sensory detector.

5, motors, motors and other electrical energy and kinetic energy conversion devices.

6, life appliances, such as induction cookers, microwave ovens and other appliances, but also a large number of magnets.
