Q. What is neodymium magnet headphones?
Neodymium magnets are lighter and smaller than other magnets, making them a perfect choice for earbuds and headphones. In fact, their sound definition and base performance is eight times better than a ferrite magnet. Neodymium magnets produce a higher sensitivity and substantial sound output using less power to do so.
Q. What does N40 magnet mean?
We can produce custom magnets that withstand high temperatures. Most of our magnets are grade N40 so if they are heated above 80˚C or 176˚F they will demagnetize and lose their strength. See Magnet Grades for more details.
Q. What is N52 neodymium magnet?
N52 is shorthand for a neodymium magnet grade with an energy product or BHMax of 52MGOe (MGOe stands for Mega-Gauss Oersteds). N52 neodymium magnets are made from one of the most expensive grades and in some instances, a lower grade of neodymium will offer adequate performance at a significantly lower price.
Q. Are Neodymium magnets safe in headphones?
Are the magnets in headphones/earbuds bad for you? There are no studies suggesting that the magnets and the relatively small magnetic fields in headphones negatively affect your brain, ears, and/or body. However, the sound levels produced as a result of these magnets may cause hearing damage if driven too high.

Q. Is N52 the strongest magnet?
NIB magnets come in different grades, which correspond to the strength of their magnetic fields, ranging from N35 (weakest and least expensive) to N52 (strongest, most expensive and more brittle). An N52 magnet is approximately 50% stronger than an N35 magnet (52/35 = 1.49).

Q. How long does neodymium magnet last?
How long will a neodymium magnet last? Neodymium magnets are permanent magnets, and lose a fraction of their performance every 100 years if maintained within their optimum working conditions. There are two factors which can shorten a magnet’s lifespan.

Q. What makes neodymium magnets different from other magnets?
Neodymium magnets have higher remanence, much higher coercivity and energy product, but often lower Curie temperature than other types of magnets. Special neodymium magnet alloys that include terbium and dysprosium have been developed that have higher Curie temperature, allowing them to tolerate higher temperatures.
Q. What are the properties of a sintered NdFeB magnet?
Grades of sintered NdFeB magnets: Some important properties used to compare permanent magnets are: Remanence (Br), which measures the strength of the magnetic field. Coercivity (Hci), the material’s resistance to becoming demagnetized.
Q. What does the negative coefficient of neodymium mean?
Neodymium has a negative coefficient, meaning the coercivity along with the magnetic energy density (BHmax) decreases with temperature.
