  • Description: 

With approaching 200kgs adhesive force, this powerful magnets should be handled with the assistance of at least one other person. As with any rare-earth magnet of this size, they can pinch, crush, or otherwise cause extreme physical harm if they are not handled with the greatest of care and respect.

Larger Round Disc Magnets are used for science projects, actuators, separators, speakers, pumps, magnetic therapy and circuit breakers in power stations.

  • Useful Tips:

useful tips1. 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)
