Neodymium MOTOR Magnets 18 OD x 14 ID x 20 L mm N45H

Description

Neodymium MOTOR Magnets 18 OD x 14 ID x 20 Long mm N45H Rare Earth
You are buying ONE lot of 10 Magnets.
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.
NEODYMIUM MAGNETS ARE NOT SAFE FOR CHILDREN
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 (see diagram below).
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.
Therefore, 2 extra arc segments will be included with each lot purchased. One of each polarity. Please be careful when assembling.
These magnets are used to create motors.
These Neodymium Iron Boron magnets are also known as "Rare Earth" or NdFeB magnets. Neodymium magnets are simply incredible!
They are far more powerful than those old horseshoe magnets most of us grew up with.
