Neodymium Ring Magnet are great for loudspeaker, home theater, multimedia, headset, water meter, vibration motor, etc.
Sintered NdFeB Magnet Ring are supplied in different grades and sizes, maximum diameter 220mm, minimum thickness 1.0mm. Ring magnet, which are magnetized through thickness (axially), north pole and south pole are located on the top and bottom. Axially magnetized is common magnetism for ring magnets. Diameterically magnetized also can be made as per customer’s different requirement.

1)By Sea: As the magnets have strong attraction and we will use the spacer to apart the magnets each other in case people will be hurt when take it out. Then, they will be packed in a white box of pieces each, several boxes to a carton. (Detailed package quantity should be made upon the real products)
2) By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield. Electronics Devices Powerful Neodymium Ring Magnets N42 OD32mm

Sintered rare earth NdFeB magnet: is one of the high performance rare earth permanent magnets, which use neodymium (Nd), iron (Fe), and boron (B) as their main ingredients
The NdFeB magnet has high remanence, high coercive force, high energy product and high ratio between performance value and product cost. Custom Made Magnet
It can be easily formed into various sizes
Smaller size and lighter weight in designing devices
Grade: N35-N52, 33M-50M, 30H-48H, 30SH-45SH, 30UH-40UH, 28EH-38EH, 30AH-33AH
High energy range from 30MGOe to 53MGOe with wonderful coercive force
For most applications, coating or plating is recommended
Coatings: Ni, Zn, gold, copper, epoxy, chemical, parylene and more
High energy
Very high Hc and Hci output
More economical than SmCo
Wonderful performance at ambient temperature
Applications: widely used in industrial areas and micro products, such as motor, sensors, loudspeaker, windmill, auto, national defense, speaker, computer, biology project, medical treatment, instrument and meter and more.

NdFeb magnets can be used for a wide variety of applications, for example:
Neodymium Electronics – Sensors, hard disk drives, sophisticated switches, electro-mechanical devices etc.
