How is the strength of a magnet measured?
Gaussmeters are used to measure the magnetic field density at the surface of the magnet. This is referred to as the surface field and is measured in Gauss (or Tesla). Pull Force Testers are used to test the holding force of a magnet that is in contact with a flat steel plate. Pull forces are measured in pounds (or kilograms).
What materials do magnets attract?
Ferromagnetic materials are strongly attracted by a magnetic force. The elements iron (Fe), nickel (Ni), and cobalt (Co) are the most commonly available elements. Many types of steel are ferromagnetic because of the iron content. Steel is an alloy of iron, carbon and other elements.
How can I identify the poles of the magnets?
There are several simple methods that can be used to identify the (Scientific) North and South poles of neodymium magnets. 1) The easiest way is to use another magnet that is already marked. The North pole of the marked magnet will be attracted to the South pole of the unmarked magnet. 2) If you take an […]
What are permanent magnets made of?
Modern permanent magnets are made of special alloys that have been found through research to create increasingly better magnets. The most common families of magnet materials today are ones made out of Aluminum-Nickel-Cobalt (Alnicos),Strontium-Iron (Ferrites, also known as Ceramics), Neodymium-Iron-Boron (Neo magnets, sometimes referred to as “super magnets”), and Samarium-Cobalt. (The Samarium-Cobalt and Neodymium-Iron-Boron families are collectively known as the Rare Earths.)

What are Rare Earth Magnets?
Rare earth magnets are extremely powerful rare earth magnets. The incredibly strong magnets are used in a wide range of industries and are also used by magicians to create illusions and other tricks. Many companies sell scientific supplies rare earth magnet, and they can also be found in a variety of products, including speakers and computers. They are also often included in kits for young scientists, or for people who are interested in exploring the properties of magnetism.
The term “rare earths” is used to describe sixteen elements of the periodic table, including ytterbium, cerium, praseodymium, neodymium, samarium and lanthanum. These elements were initially thought to be quite rare, so they were brought together under this name. The first of these elements were discovered in the 1800s, and recent scientific advances that some of these items were actually not so rare after all. These elements have a number of interesting properties that make it a subject of study by the researchers and their potential use in magnets are one of these properties.
These elements are linked with other elements such as iron and boron to make rare earth magnets, which are usually identify the primary elements of rare earth containing, as is the case of neodymium. The resulting magnets are very powerful magnetic field, which exceeds by far the most common fields of the magnets. Moreover, they are considered as permanent magnets, although the rare-earth magnet loses magnetic fields at high temperatures. Some are also very fragile, unfortunately, which means it should be used with caution because they can break down the explosive power.
Two known examples of magnets are rare earth magnets and samarium-cobalt magnets. Neodymium rare earth magnets are among the highest of all the magnets, and they are relatively inexpensive, making them very popular. SmCo magnets are brittle and expensive, but they are also suitable for use at high temperatures because they do not lose their magnetism. This makes them popular in industrial production.
Since the rare earth magnet is so strong, it is important to be careful around them. They may interfere with the function of medical devices such as pacemakers, as well as causing havoc with electrical components. The magnets can also pinch your fingers or cause damage to their property due to their strong magnetic field, which attracts metallic objects. As is generally the largest magnet, the greater the risk, and people should be careful when they are more rare earth magnet and a large metal objects.
