Neodymium arc magnets are kind of irregular shape with diameter NdFeb magnet, which also called neodymium
segment magnet. They feature as strong & stable holding force, which are widely used in fields of motor,
generator,coupling,wind power and other applications. A coating protection is necessary due to
the neodymium disc magnets are poor in corrosion resistance
Neodymium arc magnet,neodymium magnet arc,arc neodymium ndfeb magnet,neodymium
magnet and arc,arc neodymium magnet;
Magnetization:Axially magnetized or diametrically magnetized is available .Mostly they are magnetized in pair.
Coating:These round Magnet can be coating Ni, Zn, Au, Ag, Epoxy, Teflon, NiCuNi, etc;
Dimension: 1mm < = D <=250mm , 0.5mm < = H <=80mm if axially magnetized or
1mm < = D <=60mm , 0.5mm < = H <=80mm if diametrically magnetized;

Caution1.Please pay full attention to avoid any finger injury when applying the magnetized product since it possesses strong magnetic force.
2. The magnetized magnets should be kept far away from floppy disks, magnetic tapes, credit CARDS, magnetic CARDS, electronic devices and electronic instrument boards, pacemakers and other medical devices or similar objects.
3.Please pay full attention to avoid any damages or chips during transport and handling since NdFeB and SmCo magnet possesses weak impact resistance.
Neodymium Arc Magnets are used in motor ,generator,coupling,wind power industry.
