The neodymium soft-dome tweeters promise higher sensitivity without ear fatigue and a smaller footprint.
China produces the vast majority of two particularly important rare earths, dysprosium (99%) and neodymium (95%).
Recycling is tricky: just half a penny's worth of neodymium helps a mobile phone vibrate.
Now, 95 percent of neodymium comes from China, and last year, demand within China shot way up.
Dr Post's system uses magnets made of an alloy of neodymium (a rarish metal), iron and boron.
Quite truthfully, the resale value of, just as an example, 10 kg of neodymium is somewhere around zero.
Nickel-metal-hydride batteries use neodymium, cerium, lanthanum and praseodymium, none of which are used in more efficient lithium-ion batteries.
FORBES: Ford Sees Cost Breakthrough With New Family of Hybrids
Sure, you could buy 500 kg of neodymium, or 50 kg of dysprosium.
It's got nine speakers: six 8-centimeter (3.15-inch) aluminum cone mids powered by neodymium magnets and three 2.5-centimeter (1-inch) titanium dome tweeters.
By alloying neodymium with dysprosium, magnets are created that more readily maintain their magnetism at the high temperatures of hybrid car engines.
Coupled with the use of ultra-linear neodymium magnets and precision damping this ensures smoother motion and therefore a more accurate, natural sound.

Neodymium magnets are the strongest permanent magnets known, and a neodymium magnet of a few grams can lift a thousand times its own weight.
Neodymium is used in the magnets of motors in electric cars.
Neodymium is a rare earth metal used extensively to produce permanent magnets found in everything from computer hard disks and cell phones to wind turbines and cars.
Interestingly, neodymium magnets were invented in the 1980s to overcome the global cobalt supply shock that occurred as the result of internal warfare in Zaire (now Congo).
BeoPlay H6 is designed around 40 mm custom designed drivers with neodymium magnets that are perfectly angled to get the best distance and sound direction into the ears.

Of course, they didn't just use any old off the shelf magnet, instead designing custom neodymium iron-boron models that produce just the right magnetic field necessary to make that hard drive completely useless.
The newest over-ear model from Scosche features the company's proprietary headphone design that utilizes 40mm drivers made from rare-earth neodymium magnets and precision wound copper voice coiling to create an incredibly accurate musical reproduction.

Because some users turn the crank-handle faster and harder than others, a nifty three-stage gearbox and a dynamo based on powerful neodymium-iron-boron magnets is used to ensure that efficiency is largely independent of the torque applied.
Maisel said patients with pacemakers and ICDs are told that magnets can interfere with the function of their implants, but they may not be aware that headphones contain the magnetic substance neodymium, which helps with sound reproduction.
The speakers are equipped with onboard DSP, for maintaining accuracy and efficiency at all volume levels, and high-quality, custom-designed neodymium loudspeakers. iLoud is equipped with a bi-amped 4-driver array, and iLoud MINI with a pair of full-range speakers.

Say, just as an example, that I was importing the neodymium oxide which was going to be used to make the magnets to go into one of those windmills which the Greens want to festoon the country with.
Among them are the rare earth elements, in particular neodymium, production of which, it is reckoned, will have to increase five times to build enough magnets for the number of wind-turbines deemed necessary for a fully renewable future.
Peak neodymium is the latest threat to green energy, while doubt emerges over the security of many other element groups including the rare earths, the platinum group metals, and elements such as antimony, beryllium, gallium, germanium, graphite, indium, magnesium, niobium, tantalum and tungsten.
As I noted in previous posts, there is the further question of whether there will be sufficient quantities of rare earth elements (REEs) available on the world markets to make the turbine magnets, which need about one ton of neodymium per 4 MW of rated capacity.
FORBES: The Heretic: Electric Cars Should Be Called Coal Cars
The researchers twigged that this phenomenon could be used to measure density and, as they report in the Journal of Agricultural and Food Chemistry, they set about this task by erecting a stack of two off-the-shelf neodymium magnets separated by a vertical vial of paramagnetic fluid.
