Are Neodymium Magnets Used Only in Small Devices?

Many people think that neodymium magnets are only used in small devices like headphones or small speakers. But is this really true? Can we only use neodymium magnets in the production of small devices?

Neodymium iron boron magnets are not resistant to high temperatures, and Class H magnets begin to lose their magnetic properties above 120 degrees Celsius. Preventing overheating is quite difficult for large devices. However, with the help of cooling equipment, large devices can be kept at the desired temperatures.

Adding auxiliary equipment to a device increases the device’s weight, which in turn increases shipping costs. Many people believe that neodymium magnets are small in volume and therefore should not increase shipping costs. However, the high shipping costs stem from the need for cooling motors to protect the neodymium magnets.

In addition to the deterioration of neodymium magnets at high temperatures, it is believed that they are not used in large devices due to their high manufacturing costs. However, this is not entirely correct. Many major appliance manufacturers today prefer to use neodymium magnets in their products. Alnico magnets can be considered as an alternative to neodymium magnets. Alnico magnets are much more affordable. However, they cannot surpass neodymium magnets in terms of strength.

Faital Pro, BMS, and Hifi are among the leading major manufacturers using neodymium magnets in their products. All three major speaker manufacturers prefer using neodymium magnets in their products.

When using neodymium magnets in such products, there are a few key points to consider. In fact, there is only one: large-sized speakers require frequent transportation. Therefore, logistics costs should be considered. The neodymium magnet should be as small and lightweight as possible. To prevent the neodymium magnet from deteriorating and maintain proper temperature, an additional heat sink will be required, which will inevitably increase the weight of the device.

You can obtain the necessary heat sink from third-party suppliers. You can manufacture such a product yourself, depending on your capabilities. However, sourcing the product you need from a professional cooling company can be much faster and more economical.

Many costs are associated with the production of large appliances. Despite these high costs, the prices of neodymium magnets are considered reasonable.
