Product Description
Neodymium Rare Earth Magnets 2 in x 1 in x 1/2 in Block N42
Neodymium Rare Earth Magnets 2 inch x 1 inch x 0.5 inch Thick NdFeB Block Magnets
Powerful Neodymium Rare Earth Magnets Grade N42, stronger than N40, N38 and N35
Br Max: 13200 gauss
Grade N42 is the recommended Grade due to its cost effectiveness over N35/N38/N40 in Hugh Piggott's new book "A Wind Turbine Recipe Book".
Neodymium rare earth magnets are the world's strongest magnets. All magnets are not created equal! Applied Magnets offers the highest quality neodymium rare earth magnets with consistent performance at lowest price. Our strong neodymium rare earth magnets are designed & manufactured to meet stringent quality standards using the latest technology.
Neodymium rare earth magnets (also known as Neo, NdFeB, NIB or super magnets) , a type of rare earth magnets, are the permanent magnets made from neodymium, iron, boron and other rare earth elements.
Nickel-Copper-Nickel triple layer coated for maximum neodymium rare earth magnets durability and protection again corrosion
Magnetized through the 0.5" Thickness, poles are on the 2x1" surfaces.
ISO Certified, top notch quality guaranteed
Made of commercial grade, highest quality rare earth material
Approximate pull force: over 72 lbs
N42 BrMax: 13200 gauss
Applications: Wind generators, Water Processing and more
These magnets are very powerful, make sure you read safety warning before purchase
You can also purchase blades and magnet wire from our store.
Grade Makes a big difference ! The higher the grade, the stronger the magnet
N42 grade vs. N35/N38/N40
N35 is the lowest NdFeB neodymium magnet grade on the market, we don't carry N35 grade due to its lower performance making our N42 grade the better value.
N38 and N40 are lower grades compared to N42.
Coating Makes a big difference !
Hugh Piggott talks about wind turbine failure caused by magnet corrosion due to unreliable coating in his book:
"........ the magnets themselves that can lead to a major failure in under 5 years............. Once the protective plating on the magnet is punctured, the magnet corrodes and swells gradually."
Nickel + Copper + Nickel 3-layer coating vs. Epoxy single layer coating
Epoxy single layer coating is THE LEAST durable coating from our experience.
Nickel + Copper + Nickel 3-layer coating is much more durable than Epoxy single layer coating because Epoxy single layer coating is thin and quicker to wear off, even a scratch can damage the coating easily.
Epoxy+Nickel+Copper+Nickel 4-layer coating vs. Nickel+Copper+Nickel 3-layer coating
Nickel+Copper+Nickel coating provides protection against moisture and oxygen but is prone to corrosion in salt and acidic conditions.
The combination of Epoxy and Nickel+Copper+Nickel coating is the best solution against both corrosion in salt, acidic conditions and moisture, oxygen.
We recommend Epoxy+Nickel+Copper+Nickel coated 2x1x1/2 magnet due to the superior Corrosion Resistance and excellent adhesion to metal surface of Epoxy+Nickel+Copper+Nickel coating than Nickel+Copper+Nickel coating.
In summary, Epoxy + Nickel + Copper + Nickel 4-layer coating is the most durable and most effective magnet coating. Nickel + Copper + Nickel 3-layer coating is less durable than Epoxy + Nickel + Copper + Nickel 4-layer coating. And Epoxy single layer coating is the LEAST durable coating for neodymium magnets.
