Neodymium is a chemical element with symbol Nd and atomic number 60. It is a soft silvery metal that tarnishes in air. Neodymium was discovered in 1885 by the Austrian chemist Carl Auer von Welsbach. It is present in significant quantities in the ore minerals monazite and bastnäsite. Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. Although neodymium is classed as a rare earth, it is a fairly common element, no rarer than cobalt, nickel, and copper, and is widely distributed in the Earth’s crust. Most of the world’s commercial neodymium is mined in China.
Neodymium compounds were first commercially used as glass dyes in 1927, and they remain a popular additive in glasses. The color of neodymium compounds—due to the Nd3+ ion—is often a reddish-purple but it changes with the type of lighting, due to the interaction of the sharp light absorption bands of neodymium with ambient light enriched with the sharp visible emission bands of mercury, trivalent europium or terbium. Some neodymium-doped glasses are also used in lasers that emit infrared with wavelengths between 1047 and 1062 nanometers. These have been used in extremely-high-power applications, such as experiments in inertial confinement fusion.
Neodymium is also used with various other substrate crystals, such as yttrium aluminum garnet in the Nd:YAG laser. This laser usually emits infrared at a wavelength of about 1064 nanometers. The Nd:YAG laser is one of the most commonly used solid-state lasers.
Another important use of neodymium is as a component in the alloys used to make high-strength neodymium magnets—powerful permanent magnets. These magnets are widely used in such products as microphones, professional loudspeakers, in-ear headphones, high performance hobby DC electric motors, and computer hard disks, where low magnet mass (or volume) or strong magnetic fields are required. Larger neodymium magnets are used in high-power-versus-weight electric motors (for example in hybrid cars) and generators (for example aircraft and wind turbine electric generators).

If you are looking for a magnet to enter into a beauty contest, this one will probably not even come in as third runner up, but if you are looking for brute strength, you will like this magnet.
If you put this magnet on a solid, smooth hunk of iron that weighs 150 lbs. it will pick it up. I could not gather up enough iron the first time I tried.
I finally added enough iron so that the iron hanging on this little magnet weighed 150 pounds.
All that iron you see hanging onto the little magnet is rail road iron.
The magnets I use to put this strong magnet together are surplus and when these are gone, there will be no more. I wish that were not so, but there just are not any more available on the surplus market.
This magnet makes a good fishing magnet. We call it a fishing magnet, because you can go down to Lowe’s and purchase a cable to put thru the eye in the backing plate, and also purchase the crimping hardware to make it good and secure. Makes a neat unit.
You can go fishing with this extremely powerful magnet. You may not catch a whole lot of bass, but if you drag your magnet behind your boat, you may find a gun, a knife, and no telling how many fishing lures.
Do not drill, cut or grind on the magnet.
Neodymium magnets (rare earth) are extremely strong but they are also brittle. If you let one slap down on a solid piece of metal too hard, it can break. Then you have two or more strong rare earth magnets. All with a north and south pole.
This unit is actually 3 magnets on a backing plate.
The magnets are 1 1/2″ diameter, and 1/4″ thick.
The backing plate is 4 1/2″ long and 1 1/2″ wide.
The backing plate weight is quite heavy.
I sometimes work on tools or equipment in the backyard, and if I drop a small part in the grass as often happens, it is almost impossible to find it, but you can drag your magnet around the area and you will invariably find your small part.
Some of the scrap yards put these magnets on their conveyors to separate the ferrous metals from the non-ferrous metals. Saves a lot of time and energy.
If you hang some of these on the front of your lawnmower, you will find most of the nails, screws, pieces of wire or other iron that has been thrown or dropped into your yard.
If you roof your house or you have someone roof your house, there will be rusty nails, and probably some shiny new ones also dropped into your yard.
When you mow, one of those nails can knock a car windshield out, or may imbed a nail into your leg or some kid’s eye.
Magnets hanging on the front of your mower may solve that.
I use magnets in my shop. I put one on top of my drill press, so I can just pitch my chuck key in the general direction of the magnet and it will be there the next time I need it.
I also put some drill bits that I frequently use on this same magnet. That way they are always in sight. I do not have to go digging and hunting for a drill bit.
If I lay my chuck key on my workbench, I probably will not find it this month. Since it is always hanging on the magnet on top of my drill press, I never have to wonder where it is.
I do the same with the chuck key to my lathe. It is a fairly large chuck key, but I put a magnet on the lathe and my chuck key is always on the magnet, always handily in sight and easy reach.
I put magnets on some of the rafters and studs in my shop, and I hang special tools on them.
Many chuck keys and tools will not hang on a hook. Open end wrenches do not readily hang on a hook or a nail, but they will always hang on a magnet.
Allen wrenches will not hang on a nail, but they will always stick to a magnet.
Many mechanics and tool repairmen keep a magnet on their workbench to keep parts from being lost from their bench. You can put your parts in a bowl or a bucket, but the bowl or bucket will probably get turned over and the parts will scatter.
Use a magnet and this will not happen.
Find studs in your house with a magnet.
Find survey stakes.
Some, that I know down around Aransas Pass go out to the fishing piers every morning and fish around with their magnet.
They know that there are fishermen on the piers all night long, fishing, drinking beer and horse playing. Sometimes more beer drinking and horse playing than fishing.
The boys with the magnets sometimes come up with a fresh rod and reel. One that was dropped into the water the night before.
I was rolling my power plant thru the grass to the back yard the other day and the wheel fell off. The little “C” retainer that holds the wheel on had come loose and fallen into the grass. There was no way to see the little bitty part, but I got a magnet and quickly retrieved the part. The part may not have cost but 50 cents, but it would have meant a trip thru heavy traffic to the hardware store and back.
