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 magnet is made of patent licensed neodymium magnetic material with state of the art technology. it's the dimension used most often for DIY wind turbines in Hugh Piggott's plan. This special magnet has a 1/8" countersunk hole and magnetized through 1/2" so the N and S poles are on the 2x1" flat surfaces. The magnet is composed of grade N42 NdFeB rare earth magnetic material and are coated with black epoxy. The tolerances of all the dimensions are +/-0.002".

• Material: Patent licensed NdFeB, grade N42
• Gauss Rating: 13,200 Gauss
• Holding Power: 70.97 lbs each
• Pole Orientation: Magnetized through 1/2" so the N and S poles are on the flats surfaces.
• Applications: Home made wind generators (Hugh Piggott's Plan), water treatment systems, holding and science projects
