Have You Thought About Using Rare Earth Magnets?

by Kyle Marshall

Almost everyone understands that magnetism exists. Many people will have experimented with magnetism during their schooldays, but how many people realise the part magnetism plays in so many pieces of equipment today? Magnets are in hand tools, medical equipment, IT hardware and even something as mundane as a door catch. While most of these applications use traditional ferrite magnets, there are many times that more magnetic pull is needed, and that is when manufacturers frequently turn to rare earth neodymium magnets. Their ability to provide a significant magnetic pull from a small magnet is the defining characteristic of rare earth neodymium magnets, but that isn't the only thing you need to know about them.

Increased heat resistance 

Rare earth neodymium magnets can withstand heat better than a traditional ferrite magnet. If you are concerned about the operating temperature of your equipment causing a loss of magnetic field, it is worth looking at different types of rare earth magnets. With such a range available, one of them could be the solution to your problem.

Increased lifespan 

Every magnet will deteriorate over time. With traditional ferrite magnets, you should expect around 5% of the strength of the magnet to be lost for every 100 years that it operates. The advantage offered by rare earth neodymium magnets is that they will lose only a tiny fraction of that amount of magnetic power, so you can expect to keep using them long into the future.

Increased cost-effectiveness 

Rare earth neodymium magnets are getting cheaper. In the past, some designers have been reluctant to incorporate rare earth magnets into their work due to the high cost, but manufacturing advances continue to drive down costs so that rare earth magnets are no longer expensive and are now routinely included in a much greater range of products.

If you have been considering including rare earth neodymium magnets in your product, you must remember that not all rare earth magnets are the same. Rare earth magnets bring many benefits, but you must choose the right rare earth magnet for your situation. You will need to consider both the grade of the magnet and the magnet material. If you want to use rare earth neodymium magnets in an area where corrosion could be a problem, plating the magnet with nickel or zinc will reduce the risk of corrosion interfering with the magnetism.
