Frenergy stocks a wide selection of magnet types that includeFerrite,Alnico, andSamarium Cobaltbut mainly focuses on powerfulNeodymium (Rare Earth) magnetic products that contain the strongest magnetic material available today. ThesePermanent magnetsare made from the relatively new, super-strong Rare Earth minerals and have had a huge impact on how large manufacturers, engineers, scientific researchers and individual customers view and use magnets to create new or improved products and technologies.

Select the right magnet for your application by considering the shape, magnetic grade and size of the magnet you require. AlthoughNeodymium magnets are compact and super-strong, they are susceptible to corrosive forces and can become demagnetised when exposed to temperatures above 80℃. Magnets made from other magnetic materials (Ferrite orSamarium ) that have lower magnetic strength but have a better capacity for resisting heat and corrosion may be more suitable for use in these types of environments.
The range and number of applications that can be simplified or improved with magnetic products are endless.
The Frenergy website has categories of magnetic products including magnetic tools and assemblies that can benefit your business,factory,school or home.

The four types of permanent magnet are Ferrite magnet, NdFeB or Neodymium magnet, Samarium cobalt magnet and AlNiCo magnet. A Neodymium magnet is a permanent magnet made from an alloy of Neodymium, Iron, and Boron to form the Nd2Fe14B tetragonal crystalline structure. Neodymium magnets are the strongest permanent magnets commercially available, anywhere in the world. Neodymium magnets provide unparalleled levels of magnetism and resistance to demagnetisation when compared to Ferrite, Alnico and even Samarium-Cobalt magnets. Compared with ordinary Ferrite magnets, powerful Neodymium magnets have a stronger magnetic force. Neodymium magnets are many times stronger than ordinary magnets in terms of magnetic force. 

A ferrite is an iron oxide-containing magnetic ceramic material. They are ferrimagnetic, meaning they are attracted by magnetic fields and can be magnetised. Ferrite magnets are used in the electronics industry to make efficient magnetic cores called ferrite cores for high-frequency inductors, transformers and antennas, and in various microwave components. Ferrite compounds are extremely low cost, being made mostly of iron oxide, and have excellent corrosion resistance. 

A Samarium–Cobalt (SmCo) magnet is a type of Rare Earth magnet, and is a strong permanent magnet made of two basic elements, Samarium and Cobalt.  These magnets are routinely used in high-performance motors, machinery, pumps, medical devices, magnetic couplings, magnetic separators and other equipment for automotive, aerospace, medical, military and industrial automation industries. 

Alnico magnets are manufactured from aluminium, nickel and cobalt. They have a relatively high temperature tolerance of up to 550°C and are relatively corrosion resistant. Alnico’s biggest downfall is its poor resistance to demagnetisation. This instability sometimes makes Alnico unsuitable for certain demanding engineering requirements. 

Neodymium magnets are the strongest type of permanent magnets available commercially. These magnets are made from an alloy of Neodymium, Iron, and Boron (NdFeB). A Neodymium magnet is a permanent magnet and is the most widely used type of Rare Earth magnet. 

Neodymium magnets are known for their exceptional strength and these powerful magnets are used in countless applications, including motors, generators, magnetic bearings, magnetic resonance imaging (MRI) machines, electronics, communication and sensor systems.  

The strength of a Neodymium magnet is based on several factors, such as size, shape and magnetic orientation. Their magnetic strength is rated in grades from N30 – N55, which is the strongest Neodymium magnetic grade. Higher values indicate stronger magnets. Neodymium magnets are graded according to their maximum energy product, which relates to the magnetic flux output per unit volume. 

The strength of a Neodymium magnet is also measured in pull force.  A magnet's pull force is the force that's required to pull that magnet free, vertically, from a steel plate. Magnetic pull force is usually measured in pounds and is a reliable method of measuring the magnet's maximum strength. It also tells you the limit of that magnet's holding power. 

Gauss is another measurement used to determine the strength of a magnet. A magnetometer, or Gaussmeter, is used for measuring a magnetic field at a certain point in space. Some instruments can also measure the direction of the magnetic field. These instruments were invented in the mid-1800s and over many decades have evolved into accurate, precise measurement tools. 

If you want to get really technical, here's the scientific explanation of why Neodymium magnets are so powerful. The strength of Neodymium magnets is the result of several factors. The most important is the tetragonal Neodymium, Iron and Boron crystal structure. Microcrystalline grains are aligned in a powerful magnetic field during manufacture, so their magnetic axes all point in the same direction. The resistance of the crystal grains gives the compound a very high resistance to being demagnetized. 

The magnetic energy value of a Neodymium magnet is about 18 times greater than 'ordinary' ferrite magnets by volume and 12 times by mass. In practice, the magnetic properties of Neodymium magnets depend on the alloy composition, microstructure, and manufacturing technique employed. 

Neodymium is classified as a Rare Earth element. Rare Earth minerals are formed by supernovae, exploding stars, and the Rare Earths are a collection of 15 metallic elements in the periodic table. They possess a range of unique magnetic, optical and catalytic properties which make them highly valuable in our modern economy. Rare Earth minerals are key ingredients for glass, lights, magnets, batteries, and catalytic converters, and used in everything from cell phones to cars. Rare Earth elements aren't actually rare in terms of abundance but are rarely found in concentrated ore deposits. Neodymium Rare Earth magnets are the strongest type of permanent magnet available and enabling high tech gadgets to become smaller, cheaper and lighter while maintaining optimal pull strength. The superior magnetic quality of Neodymium magnets has allowed designers to improve the efficiency of multiple technologies, such as hybrid and electric vehicles, mobile phones, televisions, computers, wind turbines, loudspeakers, aircraft controls, robots, and factory automation equipment. You can thank the superior quality of Rare Earth magnets for the convenient size of your smartphone and electronic gadgets.  

Rare Earth elements are also known as ‘green elements’ for the critical role they play in making green energy products. Demand for Rare Earths will continue to grow in the future for the production of environmentally friendly products, from wind turbines, catalytic converters and hybrid cars to rechargeable batteries, energy efficient light bulbs and solar panels. Because Rare Earth magnets are lightweight and long range, they are a key factor in the development of efficient zero emission transport. 

Magnets are different to other metal and non-metal objects because the molecules in magnets are arranged so that their electrons spin in the same direction. This arrangement and movement creates a magnetic force that flows out from a north-seeking pole and from a south-seeking pole. All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field. In magnets, the electrons in atoms at one end all spin in one direction, and those in atoms at the other end all spin the opposite way. This creates a force of energy around the magnet, called a magnetic field. Magnets attract materials that have unpaired electrons that spin in the same direction.  

The process that turns a metal into a magnet also attracts the metal to magnets. When the like pole of two magnets comes close, the magnets repel each other because the direction of the line of force is opposite, and when the opposite pole comes together, they attract each other because the line of force points in the same direction. The force that causes the attraction or repulsion between magnets is known as the magnetic force. In most substances, equal numbers of electrons spin in opposite directions, which cancels out their magnetism. In substances such as iron, cobalt, and nickel, most of the electrons spin in the same direction. This makes the atoms in these substances strongly magnetic, but they are not yet magnets. To become magnetised, another strongly magnetic substance must enter the magnetic field of an existing magnet. The magnetic field is the area around a magnet that has a magnetic force. 

Strong electrical currents can disrupt a magnet's magnetic field and cause it to demagnetise. You should store your magnets away from anything that gives off an electrical current, including microwave ovens, wireless routers and computers, as they can affect the strength of a magnet. Magnets can produce a far-reaching, strong magnetic field. This magnetic field may affect, or even damage, many electronic devices, ID cards, credit cards, or any other magnetic media. Electrical appliances such as televisions, mobiles, CDs, and computers have magnetic storage devices inside them. When we bring external magnets near these appliances, the external magnets will interfere with the magnetic components of the appliances and may damage them.
