Where To Salvage Large Neodymium Magnets
Neodymium magnets are used for many different purposes and can be found in places where the untrained eye will least expect them to be. They make up the core of specific mechanics and enable huge and distinct appliances to work effectively.
People who need to salvage large neodymium magnets may have no idea where to look for them. Even when these large neodymium magnets are found, it is essential to note that it requires technical know-how to extract them from their sources. Only professional technicians can safely salvage these large neodymium magnets.
It will undoubtedly be outrageous to find machines with large neodymium magnets lying around. That is because of the size of the device and its use. Keep reading for further explanation.
Here are the various places and appliances one can look to find large neodymium magnets.
Old Scraps of Windmills/Turbines
Wind turbines are built to work in very harsh environments and must be capable of withstanding extreme conditions like high and low temperatures, wind storms, sandstorms, and even snowstorms. To this end, permanent magnets like neodymium magnets are used to ensure that these turbines last for years under these extreme conditions. We can find the neodymium magnets in the motor of the wind turbines; in the core of the mechanics of these turbines. Statistics show that these motors have about eight hundred pounds of neodymium.
These high-grade neodymium magnets obtain a high air gap magnetic density. When the motor is running and alternating demagnetizing fields exist, the neodymium magnets become essential because they possess high coercivity that enables them to withstand these alternating fields without becoming demagnetized.
Non-Functional Magnetic Resonance Imaging Machines (MRI Machines)
MRI machines produce detailed images of internal structures of the human body, including organs, muscles, and bones. They are non-radiation machines that use giant magnets and radio waves to create images on a computer. These large machines require a strong magnetic field to transmit the scanned images to a computer system. One of the four major parts of an MRI machine is the magnet. The bore, the horizontal tube the patient is laid, contains neodymium magnets from the front, extending to the back.
One of the vital components of electric motors is neodymium magnets. Electric motors are found in most refrigerators, water pumps, washing machines, and air conditioning units. Neodymium magnets in electric motors are more common than they might seem. They play a vital role in these motors by acting as the stator part of the motor providing the rejection power to create circular or linear motion. In simpler terms, the neodymium magnets make up the part of the motor that does not move.
Magnetic Cranes Used in Lifting Very Heavy Objects
Magnetic cranes, also known as lifting magnets, lift heavy objects like steel plates using a magnetic force. Different types of magnets are used in the lifting application, but we’ll focus on the permanent lifting magnet part of the machine, which uses neodymium magnets. The permanent lifting neodymium magnet has a single block with the main body and the rotor, containing two magnets each.
From Large Speakers
Speakers usually possess a cone attached to an electromagnet and a permanent magnet. Large speakers mostly make use of neodymium magnets as permanent magnets because it has the strength to produce a strong and consistent magnetic field to fuse with the variable field of the electromagnet. The neodymium magnets are located at the end of the cone in the speaker.
