Where Can I Salvage Large Neodymium Magnets?

The fascinating thing about neodymium magnets is how powerful their magnetic fields are. So it is no surprise that people always look for where to get them. These neodymium magnets possess more powerful magnetic properties than ordinary magnets, which has led to them being called “permanent magnets.” They can perform for extended periods without losing their magnetic properties.

In recent times, people have found small sizes of neodymium magnets in regular items like hard drives and headphones, and the search has only continued for much more significant finds. This article will detail where one can find large neodymium magnets and safe ways to salvage them when found.

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.

Electric Motors

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.

How To Safely Salvage Neodymium Magnets When Found

Salvaging small sizes of neodymium magnets is relatively easy, and the average person can single-handedly retrieve them from their sources. Unfortunately, this does not apply to large neodymium magnets because they possess a powerful magnetic pull capable of permanently destroying anything placed in between two of these magnets. These magnets have an attraction force capable of pulling from fairly vast distances, so they must be only handled by individuals with adequate knowledge on how to manage them carefully. Below are guides on what to do. In an attempt to salvage these neodymium magnets when found in the various places we mentioned above.

Old Scraps of Windmills/Turbines

Windmills and wind turbines are mostly locally owned by farmers, private investors, businesses, or other public entities who use wind energy to reduce the cost spent on energy provision or substitute other energy sources for the local community. It is necessary for anyone salvaging neodymium magnets from these scraps to ensure that permits and authorization are gotten from the appropriate body in charge. Once the clearance is obtained, a technician with adequate knowledge of the machinery will be required to take out the different parts of the motor that houses the neodymium magnets and safely retrieve them.

From Non-Functional MRI Machines

We will most likely find MRI machines in a standard hospital or health facility. The faulty machines that are not in use will usually be stowed away in storage units of the facility. Anyone seeking to salvage large neodymium magnets from these machines will first obtain the permission of the hospital authorities or, in most cases, completely buy it from the hospital in situations where they are willing to sell. After that, an MRI technologist will be required to disassemble the machine parts to salvage the neodymium magnets.

From Electric Motors

To salvage large neodymium magnets from electric motors, one would need to take off the parts of appliances that house these electric motors. Because these appliances are mostly household appliances, they are easily accessible. However, electronics such as refrigerators, water pumps, washing machines, and more have complex mechanics, which can be tricky for an amateur. Therefore, specific technical knowledge is required to salvage these neodymium magnets safely. In this case, an electrician will be needed to dismantle the particular appliance and salvage the neodymium magnets safely.

From Magnetic Cranes

We can find magnetic cranes primarily in scrap yards and recycling facilities. Anyone who wants to salvage large neodymium magnets from these machines will need to buy the faulty machines from the companies or individuals that own them. It’s improbable to find these faulty machines laying around freely with the neodymium magnets intact. Ensure that the owner is privy to your intention of obtaining this, and then you can take it apart.

From Large Speakers

Taking apart components of regular household speakers is relatively easy, but you will most likely find small sizes of neodymium magnets in them. To obtain large neodymium magnets, one must discover large loudspeakers like those used in concert arenas and auditoriums. Though it might seem like speakers are not exactly complex appliances, it is still important to note that large neodymium magnets are strong and must be handled carefully. Salvaging large neodymium magnets from faulty loudspeakers should be done by persons with adequate knowledge on how to handle power rare earth magnets, but one might choose to salvage them on their own.

Summary

Neodymium magnets are popular for how much strength they pack in small sizes. Smaller neodymium magnets possess a magnetic pull that is a lot stronger than more giant regular magnets. The larger sizes of neodymium magnets have a strong magnetic force which can be highly beneficial in applications and detrimental if accidents occur due to careless handling. Therefore, People must employ extra care to ensure that these neodymium magnets are safely salvaged.

In this article, we have walked you through a step-by-step process on where to find large neodymium magnets and the adequate permissions to have them extracted.
