Neodymium Magnet 2 inch x 1 inch x 0.5 inch Thick Rare Earth NdFeB Magnet Grade N42, 20% stronger than N35
0.25" x 0.14" 90 degree Dual Sided countersunk center hole on both sides of magnet to recess a #6 flat head screw head.

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".

Extremely durable Epoxy + Nickel + Copper + Nickel 4-layer Coated with tapered center hole

0.14" Diameter counter sunk center hole fits with #6 metal screws

Epoxy + Nickel + Copper + Nickel 4-layer layer coated for maximum neodymium magnet protection and durability























For wind generator magnets, coating and performance are the most important things to consider, we recommend Epoxy+Nickel+Copper+Nickel 4-layer coating for long term durability under all weather conditions, we don't recommend Epoxy single layer coating, please read details below. To have better performance for your wind generator, the higher grade the magnets, the better; N42 grade offers much better performance than N35. we recommend at least N42 or higher grade for high performance.

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 bad 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."

Multiple coating (Nickel + Copper + Nickel and Epoxy + Nickel + Copper + Nickel) vs. Epoxy single layer coating
Epoxy single layer coating is THE LEAST durable coating from our experience.
Multiple coating is much more durable than Epoxy single layer coating because Epoxy single layer coating is a thin layer of plastic and quicker to wear off, even a scratch can damage the coating easily.

More importantly, magnets with multiple coating have superior cracking and chipping resistance in comparison to magnets with Epoxy single layer coating. Customer beware of the magnets with the inferior Epoxy single layer coating.

Epoxy + Nickel + Copper + Nickel 4-layer coating vs. Nickel+Copper+Nickel 3-layer coating

Epoxy + Nickel + Copper + Nickel 4-layer coating has superior Corrosion Resistance and excellent adhesion to metal surface than Nickel + Copper + Nickel coating, this coating is ideal for bonding metal. Nickel+Copper+Nickel coating provides protection against moisture and oxygen but is prone to corrosion in salt and acidic conditions.

These magnets are much stronger than N35 grades, they provide higher output and performance than lower grade for wind generators.



Magnetized through the Thickness 0.5", poles are on the two 2x1" surfaces

Neodymium magnet is the world's strongest magnets. All magnets are not created equal! Applied Magnets offers the highest quality neodymium magnet with consistent performance at lowest price. Our strong neodymium magnet are designed & manufactured to meet stringent quality standards using the latest technology.

Neodymium magnet (also known as Neo, NdFeB, NIB or super magnets) , a type of rare earth magnet, is a permanent magnet made from neodymium, iron, boron and other minor elements.

Strong Neodymium Magnet Grade N42, stronger than N40, N38 and N35

BrMax: 13200 gauss

Epoxy + Nickel + Copper + Nickel 4-layer coated for maximum neodymium magnet durability and protection again corrosion
