Dimensions in MILLIMETERS of the completed MOTOR RING: 18 outer diameter x 14 inner diameter x 20 long(18 mm x 14 mm x 20 mm)
Nickel (Ni) Plated (silver-like shine)
Grade: N45H - Extremely powerful magnetic material.
N45 equals very strong magnetic material. The "H" represents a high heat rating. Standard neodymium magnets - those with no extra letter after the number rating - will produce their maximum strength up to 176 degrees F. Beyond 176, standard NdFeB magnets begin to lose strength. These N45H magnets will maintain full strength up to 248 degrees F - perfect for applications which require high heat tolerance - such as some motors.
These arc segments are magnetized through their thickness in order to be able to create a ring.
ASSEMBLY REQUIRED: It takes 8 arc segments - 4 with N Poles on the outer diameter and 4 with S Poles on the outer diameter - to complete a ring.
PLEASE NOTE: As with ALL neodymium magnets, these arc segments are very fragile.
