25mm x 8mm x 3mm Strong Neodymium Craft Fridge Magnets N52

25mm x 8mm x 3mm Strong Neodymium Craft Fridge Magnets N52, Neo Block Magnet, Sintered Neodymium Elevator Motor Permanent Neodymium-Iron-Boron Rectangular Magnets, Super Strong Superior Magnets Made in China

25mm x 8mm x 3mm Strong Neodymium Craft Fridge Magnets N52 Specifications
These are ideal for some Scalextric and some slot cars. Please note that several different sizes of magnets are used in these cars and you need to ensure you have the correct one.
N52 is the highest grade which is currently widely and reliably available. In a size for size comparison an N52 grade magnet will have approximately 35% more pull than the same sized N35 grade magnet.

WARNINGS:
All neodymium magnets are unsuitable for children; do not ingest.
All neodymium magnets are brittle; do not allow these magnets to jump together or to an iron/steel surface – they will break, crack, chip or shatter.
Thin neodymium magnets DO NOT FLEX, if you attempt to flex them they will snap in half.

Magnets can be custom made. We supply OEM service. Rare-earth, Neodymium-Iron-Boron (NdFeB) Permanent Magnets For more information, please CONTACT US. Rare Earth NdFeB Disc Cylindrical Magnet N48M Color Zinc Plating
These are ideal for a large range of science applications, DIY and MRO uses. If you need to use an adhesive, we recommend using something that will bind to metal and whatever surface you want to glue the magnet to.

The pull is calculated using a mathematical formula and is, therefore, the theoretical maximum hold between one magnet and a mild steel plate. It does not take account of manufacturing tolerances, plating, plating thickness or variances in a mild steel plate. The vertical hold is based upon the calculated pull and is, therefore, only for guidance. Factors such as paint thickness, plasticised surfaces, movement and vibration are not taken into account.

Axially Magnetised Rectangular Nd Magnets

As the strongest permanent magnet in the world, sintered NdFeB has excellent permanent magnetic properties and high cost performance compared with traditional permanent magnet materials. Sintered NdFeB magnets greatly expand the applications of permanent magnets. They are widely used in the fields of transportation, energy, communications, home appliances, machinery and medical equipment. Disk Rod Magnet Disc Cylindrical Magnet

Neodymium magnets offer the highest (BH)max and high Hci(BH)max, the maximum energy product, of neodymium magnets is highest of any kind of permanent magnets today in the world. (BH)max at different grades of neodymium magnets is 27 to 52 MGOe. Disc Rod Magnet, Elevator Motor Magnets Sintered Neodymium N50UH
