Product Description

Standard sizes ship within 2 weeks. custom-made size and grade are always available.

A permanent magnet is that a magnet that is permanent, in contrast to an electromagnet, which only behaves like a magnet when an electric current is flowing through it.
Permanent magnets are made out of substances like magnetite (Fe3O4), 
the most magnetic naturally occurring mineral or neodymium, Samarium cobalt, a powerfully magnetic synthetic substance.
The Earth itself is a huge permanent magnet, though its magnetic field is quite weak relative to its size. Humans have used the magnetic field of the Earth for navigation since the compass was invented in ancient China.
Even the most powerful permanent magnet is not as strong as the strong electromagnets, so their applications are limited, but they still have very widely application, magnets can be found everywhere, including your hard disk, ATM and credit cards, speakers and microphones, electric motors, and toys.
Every permanent magnet generates a magnetic field, which circulates around the magnet is a distinct pattern. The size of the magnetic field is related to the size of the magnet and its strength. 

GME Magnets offers the highest quality Neodymium magnets with consistent performance and lowest price. 
Our Neodymium magnets are designed and manufactured to meet with quality standards using the latest technology. 

Here introduce a super strong permanent magnet that very popular in European magnet mareket, especially in German.

This neodymium magnet is made of top quality grade N42 NdFeB magnetic material and magnetized through 1/2" thickness. The countersunk holes are made for #8 screws. The dimension of the magnet is 2 x 1 x 1/2" with tolerances of +/- 0.002". This magnet is majorly used for home made wind turbines described in the A Wind Turbine Recipe Book and the DIY package. The following is the magnetic characteristrics of the magnet:

• Material: Sintered grade N42 NdFeB
• Gauss Rating: 13,200 gauss
• Holding Power: 71 lbs
• Pole Orientation: magnetized through thickness, i.e. the N and S poles are on the 2 x 1" surfaces
• Coating: Ni+Cu+Ni triple layer coated, the best coating available
• Applications: Wind Generators (Hugh Piggott's Plan), Science Projects.
