Neodymium magnets are so strong that it takes effort and skill to pull one off a ferrous material. When two or more magnets are stuck together, one would have to slide rather than lift to separate them. Because of how hazardous these rare-earth magnets can get, some ordinary people leave them for engineers and technicians. The truth, however, is that small magnet can be used by ordinary people in their garages, workshops, homes or offices. Neodymium cylinder magnets are certainly good picks for home use. There have multiple useful applications. Sintered or bonded, cylinder or disc Neo magnets are perfect for home use.
When a magnet is sintered, we say that it has been die-pressed and molded into shape. Neodymium, iron and boron powder is put in a multi-cavity die and then it is pressed to become finer. Then the mixture is tossed into a very hot furnace (sintering) to become rock-solid. During the die-pressing stage, a magnet’s direction of magnetization or orientation is set. So some isotropic magnets without a definite line of orientation or anisotropic magnets with a definite line of orientation are produced through sintering.
Sintered neodymium cylinder magnets can have between 30 to 52 MGOe and so they are very powerful. The other method of compression bonding entails mixing neodymium, iron and boron powder with special epoxy adhesive to bind and compress it into a die cavity without a magnetic field. So compression bonded NIB magnets are usually isotropic. The epoxy adhesive magnet makes these pieces resistant to harsh industrial fluids. Because of their low machining expenditures and prices, compression bonded NdFeB magnets are the best picks for a range of applications. Many customers can attest to the fact that many cylindrical neo magnets for home use are tiny, powerful things. Some can even be half the size of a shirt button yet immovable when stuck to a ferrous object.
They are therefore easy to have around the home as they occupy a small room and will never hide another item beneath. Neodymium cylinder magnets are used to hold photos, receipts and other documents on a fridge or another metallic surface. They are also perfect to hold sheets of paper on bulletin boards. Many teachers use them for physics experiments or projects. To ensure that powerful items are ordered, one should consider reading the product description page. It will indicate the N-rating of a magnet or its grade.
For a really powerful experience with neodymium magnet, one should pick an N48 grade or over. Note that a cylinder magnet is often axially magnetized. Therefore its poles are situated in the middle of the flat sides. Another factor to consider is whether a magnet boasts nickel coating or not. Thicker Nickel coating makes magnets stronger and durable. They will hardly shatter when collided with hard surfaces. A prospective customer should also find out the amount of small neodymium cylinder magnets they would receive for a given price. An internet-based store owner will certainly indicate the quantity detail amid others such as size, pull force and usage directions.
