Standard Neodymium magnets have a heat tolerance of 80C and exposing them to temperatures higher can affect the magnet. The performance of the magnet can restore once cooled unless the temperature raised to the Curie temperature, which is the temperature that magnets permanently lose their magnetic properties.

Neodymium magnets, also called Rare Earth Magnets, are commonly utilized for mechanical and industrial applications where a very strong magnet is required. Their impressive size to strength ratio, as well as their good resistance to temperature fluctuations make them the preferred magnets in the mining, construction, printing and designing fields.
Rare Earth magnets are also prevalent in medical equipment: small Neodymium magnets are used to maintain dental implants and prostheses, and very large magnets are employed in MRI scanners. They are also the first choice magnets for vehicle ABS sensors.
Make no mistake: even the tiniest Neodymium magnet can hold incredible weights! Their powerful magnetic field is far superior to Ferrite or Alnico magnets! Moreover, these permanent magnets utilize several protective coatings (Nickel, Phosphorus, or Zinc) that give them a very reasonable resistance to corrosion. That is why Neodymium magnets are the premium choice in the engineering and manufacturing industries.

In nature, neodymium does not exist in metallic or in mixed forms with other lanthanides but is refined for general use and has been mined in the USA, Brazil, India, Australia, Sri Lanka, and predominantly in China.
Neodymium-iron-boron magnets were developed by General Motors and Hitachi in the 1980s. Because it provides high magnetic force even in lesser amounts, it has been increasingly given a more prominent role in the manufacture of strong permanent magnets made up of rare earth elements. In the field of information technology, neodymium magnets are particularly used in hard disc drives, mobile phones, video and audio systems of television [1].
The flow of red blood cells in the skeletal muscle capillaries exposed to strong static magnetic fields has been reported to be reduced [9], Intra tumoral microcirculation is characterized by tortuous micro vessels with chaotic structures and unstable irregular blood flow. A study has reported a decrease in the blood stream and blood vessel density in tumors that were treated using static magnetic fields. In the same study, it was shown that in non-tumoral skeletal muscles exposed to static magnetic fields, platelet activation and adhesion increased [9]. The magnetic field generated by neodymium magnets is thought to increase microcirculation but the effects on this are not clearly known.
In a study, a special device was surgically placed on the backs of laboratory mice. Neodymium magnets were attached to the device in one group, and non-magnetic, equal-sized, and same-weight platters were attached in the other group. The arteriole and venule diameters of the mice exposed to static magnetic field generated by neodymium magnets were demonstrated to be considerably reduced [10].
Another study, conducted in 2015, where the portal veins of dogs were cut and reconstructed, the anastomosis in one group was performed using traditional manual sutures and that in the other group was by covering it with rings comprising of neodymium magnets. In the latter, the recovery lasted for a considerably short time and the intima was smoother and regularly formed than in the former [11].
Recurrent transcranial magnetic stimulation (rTMS) is an approved and effective treatment method for major depression. Synchronized TMS (sTMS), which is the modified form of rTMS, has also been tried for the treatment of the same. A study conducted in 2014 revealed that while the occurrence rate of patients who suffered from major depression and treated with sTMS declined by 48%, it declined by 19% in the control group, and this difference was statistically significant. Neodymium magnets are used in TMS to generate magnetic fields and In contrast to electroconvulsive treatment for major depression, TMS does not require anesthesia [14]. Further, another study conducted in 2015 revealed the use of sTMS to be effective in the treatment of major depression [15].
In another study conducted using a trabecular damaged rabbit model, a magnetic scaffold was placed in the damaged area of the distal femoral epiphysis and cylindrical neodymium magnets (NdFeB) were placed in a nearby area, the interaction observed. At the end of the experiment, it was found that NdFeB protects against micro movements by keeping the magnetic scaffold constant and it is important in maintaining regular tissue regeneration [20].
In a randomized double blind placebo controlled research, the curing effect of neodymium magnets on osteoarthritis symptoms was investigated; participants were made to try on four types of wrist straps. During the comparison, magnetic neodymium wrist straps were used as an experimental device, and low magnified, demagnetized, and coppery wrist straps were used as control devices. The WOMAC Osteoarthritis Index, McGill Pain Questionnaire-Pain Rating Index (PRI), visual analog scale, and medicine intake were evaluated. Among these scales, only PRI subscales revealed statistically significant difference. Therapeutic benefits of wrist straps have attributable placebo effect. These devices have no major adverse effects therefore can be used for placebo effect [21].
In a research in which the role of static magnetic field in carpal tunnel treatment was researched on, the effects of two different magnetic field levels on the median nerve were evaluated. In a randomized double blind placebo controlled research, 12-week long observation was performed after a 6-week long interference. Participants who were diagnosed with carpal tunnel syndrome using electrophysiological tests wore neodymium magnets and non-magnetic disks all night long. Boston Carpal Tunnel Questionnaire, symptom severity score (SSS), function severity score (FSS), and four parameters measuring the median neural activity were used. These parameters included sensory distal latency, sensory nerve action potential amplitude, motor distal latency, and compound motor action potential amplitude. Among the groups, no significant difference was found in SSS and FSS median nerve conduction. A recovery in symptoms was observed in a 6-week period for SSS and FSS in both groups. The change of symptoms in both magnetic and non-magnetic disc groups occurred in the same direction and size [23].
In an animal study, ring-shaped magnets were endoscopically used for magnetic compression anastomosis (magnamosis), being placed opposite to each other in the targeted areas [28, 29]. Magnets have also been surgically used in humans; unwanted tissues in the operative area were safely removed using magnetic forceps in 44 laparoscopic operations, including cholecystectomy, gastrojejunostomy, and splenectomy, performed on pediatric patients between 2009 and 2011 [30].
A study reported that the attachment of oxide nanoparticles to the astrocytic membrane and their entrance into the cells becomes easier by virtue of the magnetic field generated by neodymium magnets laid under the astrocyte cells in the brain [34].
Human stem cells in serum-free medium, to which an amount of magnetic nanoparticles containing iron (0.043 mg/ml) was added in a nontoxic level, were used along with neodymium magnets and observed on a daily basis. No effect on stem cell prepotency and proliferation was recorded was reported in this study [35].
In a study conducted on pigs in 2014, vascular stents were rendered magnetic by means of neodymium magnets and, thus, ensured to hold to endothelium cells that were supported with iron particles. This may lead to an important development in stent-related procedures because the acceleration of endothelialization would reduce the risk of thrombosis [36].
An animal study published in 2012 had the orientation of stem cells containing iron particles to the targeted area in the retina again ensured with neodymium magnets. This appeared to be particularly important in the treatment of age-related macular degeneration and retinitis pigmentosa [37].
Nanoparticles loaded with cytotoxic chemotherapeutic agents can be oriented toward tumors. In tumor areas, capillary permeability increases and particles that cannot intercellularly travel elsewhere can pass into the tumor. This passage of nanoparticles can be reinforced through orientation by magnets [38].
In an experiment on aneurysm closure, magnets placed on the outer body of experimental rabbits were used to direct magnetic micro particles in the circulation toward the area for at least 30 minutes. Although aneurysmal recanalization was observed 12 weeks later during follow-up, this was an important study for possible new modalities in the treatment of aneurysms [39]. 041b061a72
