the maximum  operating temperature is 80 °C, and it never will demagnetization.

1. Acoustic field: the speaker, receiver, microphone, alarm, stage audio, car audio and so on.
2. Electronics: permanent magnetic actuator vacuum circuit breakers, magnetic relays, meter, sound meter,
a reed switch, sensors.
3. Electrical field: VCM, CD / DVD-ROM, generators, motors, servo motors, micro-motors,motors, vibration motors.
4. Machinery and equipment: magnetic separation, magnetic machinery.
5. Healthcare:  medical equipment, magnetic health products and so on.
6. Wedding corsage badges, etc., can be replaced with a magnet attracts
every other clothes pins, so as not to damage the dress.
7. For the overlying metal drawing board for fixing the drawing paper. Magnetic blackboard whiteboard fixed file drawings.
8. Advertising magnets available to replace the original fixtures, at any time convenient to replace the ad content.
9. Models piling, you can use small magnets to connect two widgets.
10. Studio, bulk magnet can be used to adsorb screws and other parts, even wrenches and other tools
1. Strong magnets should keep away from Ironware and some  easily magnetized iron products, such
as monitors, bank cards, computers, televisions, mobile phones and other.
2. Strong magnets should be stored in a dry, heated environment, and need to use of plastic, wood,
cardboard, foam to separated and wrapped.
3. Magnets might be interested in water meter ,electric meter, gas meter and some metering equipment
exist some inaccurate affect (such as: if magnets placed near  the meter, the meter will slow down).
