Permanent magnets can be installed in different ways. The way you use them has to work for the specific situation for which you are installing the magnet. Magnets can be used in a plant for food processing, for cleaning debris of a metallic nature from food. The way you would install the magnets for this process in the metal chute will be much different from how you would attach the same on your home wall. Before starting any project you need to chart out the work the magnets have to do and where you are going to fix them. Here are a few ideas which will work in most cases but they may not be ideal for all situations.
The preferred way of installing magnets is by using screws. A hole needs to be drilled in the magnet and into the material which is under the magnet, so that you can place a screw through it. This is ideal when you are installing the magnet in a wooden wall. Washers will be needed if the screw head you are using is quite small, but this is not a requirement always. Screws prove to be ideal for fixing because they are easily removable, if some kind of mistake has been made.
When permanent magnets have to be attached to surfaces which are metallic, then screws cannot be used. Here too, drilling of a hole is needed through the magnet and metal. Then instead of a screw you will have to put a bolt in the drilled hole and the nut will have to be attached on the reverse side. The nut has to be threaded down tightly so that it is firm.
In certain situations you might have to make a wooden frame or of a similar material so that the magnet can be fitted in the frame. You could visualize this installation in the way a glass pane is fitted into a photo frame. The magnet takes the place of the glass and is fitted into the frame grooves. This way the magnet will be held in place without having to use any extra hardware. Also in this process no drilling of a hole is required for the magnet, and that will ensure that the magnet does not get cracked or broken during installation.
These are not the only ways of installing permanent magnets and there are other ways as well to fit a magnet properly. Some people like to use an adhesive or glue for installing the magnet. It all depends on the situation and if the situation is not ordinary you might have to find some unique solution. Just make sure that you have considered all the uses the magnet will provide in future before you install them, so that the way you install them is correct and will not hinder their uses.
Permanent magnets are magnets permanently and are different from those which behave like magnets only when electric current is passed through them. Magnets are made of materials like magnetite or neodymium. Magnetite is a mineral which occurs naturally while neodymium is a synthetic material.
Since these are not as strong as the electromagnets their applications are also limited. However, they have various uses. Like any magnet these magnets are also capable of producing a magnetic field around in a particular pattern. The size of the magnet decides the size of the field. A permanent magnet has two poles, the south and the north.
These magnets have to be used with care because they can cause some trouble by erasing the data from your computer hard drives or your ATM card. If you want to erase any data and make it irrecoverable all you have to do is run a magnet over it. Usually, the deleted data is actually hidden somewhere and not totally removed when deleted. But using a permanent magnet you can erase it completely.
Permanent magnets retain their magnetism and are used for various purposes. They are used in different kinds of tools like screwdrivers to keep the screws attached and not lose them. But you need to be careful with them while working with discs and hard drives. Another use is in electric and hybrid vehicles. These magnets are specially used in vehicles which are made of materials containing high proportion rare earths. Some types of jewelry also use these magnets. Some necklaces, earrings and bracelets use them for keeping the jewelry clasped.
There are various kinds of scientifically engineered permanent magnets. Some of them are alnico, bonded, fabricated, hard ferrite, neodymium and somarium cobalt magnets. Alnico magnets are made by combining nickel, aluminum and cobalt. They come in different sizes from less than a gram to 22 kg. They are strong, durable, highly resistant to corrosion and stable in hot temperatures. Various complex shapes can also be produced from this.
Bonded types are injection molded which means that they can be shaped into requires forms. They generate moderate amounts of energy and are highly resistant to oxidation. When not stored in cold temperatures they tend to decay soon. Fabricated magnets have less strength when compared to the bonded types. They are made of pliable resins and binders like vinyl etc. The inexpensive varieties have moderate strength and are stable in moderate and cold temperatures.
Hard ferrite magnets are made of barium compound and iron oxide. They are widely used due to their inexpensive nature. The neo magnets are available in a wide variety of classifications and dimensions. They are usually used in different types of motors, MRIs, amplifiers etc.
The somarium cobalt magnets are used for small motors for snowmobiles and boats. They are highly resistant to oxidation and offer great high-temperature operation, magnetic intensity and high-energy production. Since they are made of rare earths they are brittle. These magnets are expensive also.
