Rings Countersunk N52 Super Strong Rare Earth Neodymium Magnet North South Poles

Description

N52 Super Strong Neodymium Magnets Rings and Countersunk Rings
General Specifications:
Plating/Coating: Ni-Cu-Ni (Nickel)
Magnetization Direction: Axial (Poles on Flat Ends)
Max Operating Temp: 176ºF (80ºC)
Material Features:
Neodymium Magnets are made of a brittle material (NDFEB). These magnets are not as strong as steel, they are more like a brittle ceramic.
If you let two magnets slam together, they can crack and break, this is true for magnets large and small.

WARNING!
The neodymium magnets we sell are extremely strong, and
must be handled with care to avoid injury and damage.
Fingers can get severely pinched between two attracting
magnets. Neodymium magnets are brittle, and can peel, crack
or shatter if allowed to slam together. Eye protection should
be worn when handling these magnets, because shattering
magnets can launch pieces at great speed.
The strong magnetic fields of these magnets can damage
magnetic media such as floppy discs, credit cards, magnetic
ID cards, cassette tape, videotapes and similar items. They can
also damage televisions, VCRs, computer and CRT monitors
and other electronics. Never place neodymium magnets near
any of these items.
Children should not be allowed to handle neodymium
magnets, as they can be dangerous. These magnets are not
toys. Small magnets risk a chocking hazard and should never
be swallowed or inserted into any part of the body.
Never allow neodymium magnets near a person with a
pacemaker or similar medical devices. The strong magnetic
fields can affect the operation of such devices.
Neodymium magnets are brittle and prone to chipping and
cracking. They do not take kindly to machining. Neodymium
magnets should never be burned, as burning them will create
toxic fumes.
