Single-Coil-Sized Humbucker For Strat?With Alnico Magnet

Look for Samarium Cobalt magnets in the high end electric motors used for slot car racing as well as in turbo machinery and traveling-wave tubes. They are also effective for use in cryogenic applications due to their wide temperature stability.Neodymium Iron Boron magnets are much like samarium cobalt magnets but can be oxidized more easily. Due to the fact that these magnets can easily be corroded, manufacturers often use a surface coating to prevent oxidation. They are also high cost magnets but offer a compact design. They do not offer the mechanical strength of the other three types of. These magnets offer high energy production and are found in microphones, in ear headphones and loud speakers as well as guitar and base pick-ups. These magnets are also commonly used in computer hard drives.

Magnets are essential for use in hard drive memories to provide needed data storage. Without magnets, recording of music would be much more difficult. Permanent magnets are essential to production of green energy and many other uses.

A rare earth magnet is a strong magnet that contains a number of materials such as cobalt, nickel, and iron. In most cases the units are derived from: alnico, ceramic, samarium cobalt, and neodymium.The strongest magnets are those made from neodymium. The good side with these units is that they easily fit in a 10-pound steel block.Magnetic strengthThe magnetic strength in the units is determined by figuring out the ability of a specific alloy to be magnetized.One of the features used in determining the magnetic strength is Gauss per cubic inch which usually measures the intensity of a magnetic flux. There is also oersteds which is a measurement of the coercivity of the magnet.

The magnetic strength is determined by multiplying the Gauss per cubic inch and oersteds. When you multiply the two you get MGOe (megagauss oesterids).ApplicationThe rare earth units are applied in a number of areas. Some of the most common applications are: computer hard drives, audio speakers, fishing reel brakes, high performance AC servo motors, wind turbine generators, traction motors, mechanically powered flashlights, and permanent magnet motors.They can also be used in industrial applications where they are used in maintaining product purity, quality control, and equipment protection.How to make the magnetsIf you have the skills, you can easily make the units. To make them you need: iron boron, neodymium, and steel.The first thing you need to do is to grind solid ingots of iron boron and neodymium into powder and compact the powder into a mold.You can compact the powder in steel or rubber molds. Steel molds are meant to provide the final shape of the magnet while rubber molds are aimed at producing rough bricks for the neodymium that is supposed to be shaped much later. For ideal shape you should press the rubber mold on all sides at once.

After doing this you should apply a magnetic field to the rare earth magnets. For ideal results you should use a magnetic field in the 4 tesla range. The magnetic field should be from a powerful electromagnet.You should then heat the magnet in a vacuum to about 1,000 degrees Celsius. Purchasing permanent magnets for your home, crafts, and electronics projects can help you create top quality items. alnico magnet
