Magnets are an extremely useful tool for a wide variety of applications, from holding notes and pictures to your fridge to powering large complex machinery. However, finding the right magnet for your application can be a daunting task.<\/strong><\/p>\n\n\n\n

With so many shapes, sizes, and materials to choose from, each with its own unique properties where do you begin to select your magnet.<\/p>\n\n\n\n

Well luckily for you we\u2019ve got some guidance on how to choose the right magnet for your project, including information on magnet size, shape, strength, and material. <\/p>\n\n\n\n

Magnet Strength<\/strong><\/h2>\n\n\n\n

The first thing to consider when choosing your magnet is its strength, the strength of a magnet can be measured in Gauss or Tesla, with higher numbers indicating stronger magnets.<\/p>\n\n\n\n

However, the pull strength of a magnet is another measurement of strength, a magnet\u2019s pull strength is the force that’s required to pull that magnet straight free vertically from a steel plate.<\/p>\n\n\n\n

The strength of the magnet you require will be completely dependent on your application, for advice please be sure to contact our team for free no obligation advice.<\/p>\n\n\n\n

Magnet Size<\/strong><\/h2>\n\n\n\n

An important factor is the size of your magnet, this may already be determined by specifications from your application, but finding a magnet the correct size is an important step in choosing your magnet.<\/p>\n\n\n\n

Typically, smaller magnets are weaker but are more versatile and easier to use in certain applications, whereas larger magnets are stronger and better suited for heavy-duty applications, but they can be more expensive.<\/p>\n\n\n\n

Magnet Shape<\/strong><\/h2>\n\n\n\n

Magnets come in many different shapes, including bars<\/a>, rings<\/a>, discs<\/a>, horseshoes<\/a>, cubes<\/a>, and rectangles<\/a>, the shape of the magnet you choose will have a direct impact on its usefulness.<\/p>\n\n\n\n

The shape of the magnet you require will be dependent on your application, for example, a disc magnet<\/a> may be used for more mechanical projects whereas horseshoe magnets<\/a> are more commonly used for holding objects.<\/p>\n\n\n\n

Magnet Material<\/strong><\/h2>\n\n\n\n

Magnets come in a variety of different materials, each with its own unique properties. The most common magnet materials are neodymium<\/a>, ceramic<\/a>, alnico<\/a>, and samarium cobalt<\/a>.<\/p>\n\n\n\n

Neodymium magnets are the strongest material available, whereas ferrite magnets are much more cost-effective, samarium cobalt magnets have a greater temperature resistance, and alnico magnets are also very strong.<\/p>\n\n\n\n

Temperature Considerations<\/strong><\/h2>\n\n\n\n

The temperature which a magnet will have to withstand in your application must be taken into consideration when choosing a magnet. Some magnets lose their strength at high temperatures and others may become permanently demagnetized.<\/p>\n\n\n\n

Standard-grade neodymium magnets<\/a> have a maximum operating temperature of 80 degrees Celsius. When heated above this, they will experience irrecoverable losses in performance. High-temperature grades of neodymium magnets with higher maximum operating temperatures are available.<\/p>\n\n\n\n

Samarium cobalt magnets<\/a> are not as strong as neodymium magnets at room temperature but have a better temperature coefficient for both remanence (Br) and resistance to demagnetization (Hci) than neodymium magnets.<\/p>\n\n\n\n

Alnico magnets<\/a> also have the highest maximum operating temperature of all the permanent magnet family, not suffering irreversible losses in performance until the temperature reaches 525\u00b0C.<\/p>\n\n\n\n

Unique among permanent magnets, ceramic magnets<\/a> actually become more resistant to demagnetization as their temperature increases. Conversely, their strength decreases as their temperature rises, albeit at a lower rate.<\/p>\n","protected":false},"excerpt":{"rendered":"
