If you’ve been recently introduced to samarium cobalt magnets or other rare-earth magnets, you may have a lot of questions about them.
Magnets such as these have uses everywhere, and we don’t even realize it.
So, what is cobalt magnetic components used for? If you’re interested in samarium cobalt magnets, keep reading to find out about their uses.
What Are Samarium Cobalt Magnets?
Samarium cobalt magnets are rare earth magnets with several industrial uses. They have a composition of cobalt and samarium as well as some other rare-earth materials.
What makes samarium cobalt magnets stand out from other rare-earth magnets is their ability to withstand extreme hot and extreme cold temperatures.
These magnets also have high corrosion resistance. All this goes to say that they are a popular magnet choice in industrial settings. Many items we use daily have a samarium cobalt magnet inside of them.
Medical Devices
One place samarium cobalt magnets are often found in the medical industry. Many devices use samarium cobalt magnets because of their versatility.
You may find these magnets in any of the following medical equipment.
- MRI components
- Servo motors and sensors
- Drug delivery systems
- Catheter navigation systems
- Dispensing equipment
- Blood analysis
Motors
You can find samarium cobalt magnets in high-performance motors and electric motors. Permanent magnet motors that use these magnets run without excitation winding.
The advantage of this is that they are small, powerful, energy-efficient, and produce little noise. In slot car racing, cars use high-end electric motors which run with the help of these magnets.
Pump Couplings
Samarium cobalt magnets are a great choice for a rare-earth magnet when it comes to making industrial pumps. Many industrial pumps, such as electrical submersible pumps, need to operate in extreme temperatures.
Samarium cobalt magnets are good because they can withstand temperatures up to 500 degrees Fahrenheit or as low as -460 degrees Fahrenheit.
Aircrafts
This type of cobalt magnetic material is often used by the military for their aircraft. Regular aircraft are spotted easily by enemies or anyone else in the air.
When an absorbing material like samarium cobalt magnetic material is used on the surface of an aircraft, it is unable to be spotted by enemies.
This works because the magnet absorbs the electromagnetic waves given off by the enemy’s technology. This practice can hide almost any plane.
Music Production and Listening
Samarium cobalt magnets are commonly used in headphones and audio speakers. In electric guitar pickups, most often produced from 2004 to 2010, samarium cobalt magnets are in the amplifier.
As for the headphones, you can still find many vintage high-end headphones made with samarium cobalt magnetic products in the 1980s.
How Cool Are Samarium Cobalt Magnets?
Samarium cobalt magnets have applications everywhere, even in your home. Their strength even in extreme temperatures makes them indispensable in several industries that use them consistently.
