Magnetic 12 Inch Speaker Neodymium Magnet Supplier – Magnet Cup With External Nut and Greater Pulling Strength (MD) – Magnetic

Magnet Cup(MD series)

Product Description

The steel cup or steel enclosure increases the pulling force of the magnets, it redirect pull force to the same surface and giving them an incredible holding force for any steel metal/ferromagnetic objects.
What’s more, these magnet cups are resistant to chipping or cracking, convenient for movement and positions. as neodymium magnets nature are brittle, easy to damage when handling.
With epoxy glue to bond the magnets and the steel enclosure, the magnet cups are quite solid and strong, strengh increased more than 30% than naked neodymium magnets.

10. Transport information
Pack up prudently so as to prevent products from breakage.
Regulations for transport: When transport magnetized by air, follow the dangerous goods regulation of IATA (international air transport association).

UPS mentioned Magnets can be shipped internationally, if they do not exceed 0.159 A/m or 0.002 gauss measured seven feet from any surface of the package or if there is no significant compass deflection (less than 0.5 degree).
The requirement from IATA that it is not resticted if the magnetism is lower than 200nT(200nT=0.002GS) measured at a distance 2.1 m
