How to Identify and Resolve Common Issues ?
We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :
The NdFeB magnet is the strongest permanent magnet in the world. It is a tetragonal crystal formed of neodymium, iron, and boron. This kind of magnet is the most commonly used rare earth magnet nowadays and is widely used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools.
The Neodymium Magnet (also known as NdFeB, NIB or Neomagnet) is the most widely used type of Rare Earth Magnet. It is a permanent magnet which has been made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure.
The advantages of the NdFeB magnets: NdFeB magnets have the best magnetic properties, good price, good strength, and are easy to process into special shapes. The disadvantages of the NdFeB magnets: NdFeB magnets are not resistant to high temperature and corrosion, and are fragile.
The induction heating method can demagnetize the large NdFeB magnets by heating the magnet to about 300 °C on the surface facing the induction heater, whereas a demagnetization using a gas torch might result in a much higher local surface temperature.
Unlike all other objects, the atoms within magnets are all spinning in the same direction. This atomic flow inside of each magnet creates an invisible magnetic force or field around the magnet that can attract or repel other magnets – and attract other metal objects.
The theoretical magnetic energy product of NdFeB can reach as high as 64 MGOe [1]. The experimental value of the energy product of NdFeB has reached 56 MGOe [2], but the low coercivity (9.8 kOe) may limit its applications.
These magnets are manufactured by melting the mixture, consisting of neodymium, iron and boron followed by casting into ingots. The ingots are subsequently pulverized to powder, which, in turn, is sintered and magnetized to form the permanent magnet.
In the Nd-Fe-B sintered magnets, due to the surface machining or oxidations, the surface grains have reduced anisotropy field and hence almost no coercivity.
Neodymium magnets are also used in wind turbines, aeronauti cs and space. Other uses of neodymium include making a specialized glass used in protective goggles for welding and glass blowing, and in applications such as surgical lasers and laser pointers.
Bonded NdFeB properties defined in FEMM are meant to be representative of typical examples rather than strictly based on the products from one vendor. Since bonded magnets consist of permanent magnet powder with a polymer binder, the electrical conductivity is very low.
Typical values of Recoil Permeability are about 1.05 for sintered Ferrite, SmCo and NdFeB. Bonded ferrite is also about 1.05. Bonded Neo magnets range from about 1.1 to 1.7, depending upon grade.
Neodymium magnets, also called NdFeB magnets, are tetragonal crystals formed by neodymium, iron, and boron. According to different production processes, they can be divided into three types: sintered NdFeB magnets, bonded NdFeB magnets, and hot-pressed NdFeB magnets.
Properties of neodymium
The metal has a bright and silvery luster. Neodymium can be found in two allotropic forms, transforming from a double hexagonal to a body-centered cubic. Naturally-occurring neodymium has seven stable isotopes. Fourteen other radioactive isotopes are known.
Magnets can damage your electronics
Strong magnetic fields of neodymium magnets can damage certain magnetic media such as credit cards, magnetic I.D. cards, and legacy media such as cassette tapes, and videotapes. They can also cause damage to TVs and computer monitors.
Neodymium magnets are attracted to ferromagnetic materials, which are materials that are capable of being magnetized and are attracted to magnets. Ferromagnetic materials include iron, steel, nickel, cobalt, and some alloys of these materials.
Neodymium magnets are so strong because of their high resistance to demagnetisation (coercivity) and their high levels of magnetic saturation allowing them to generate large magnetic fields.
How Strong Are Neodymium Magnets? Very strong. They will amaze you! A 2-gram (0.07 ounce) neodymium magnet that measures 8 millimeters (0.315 inches) in diameter and 5 millimeters (0.197 inches) long generates a force of over 1700 grams (3.75 pounds).
The electrical resistivity range of NdFeB is between 1.2 μΩ·m and 1.5μΩ·m.
Pieces of iron or other materials are made magnets by rubbing them with natural magnets (or by passing direct current through a wire wound around them). This is how artificial magnets are made.
The maximum recommended temperature for the NdFeB magnets is +230 degrees C, whereas the SmCo can work at +300 to +350 degrees C.
weight of the magnet:~ 5,9 g. direction of magnetization: along the dimension of 10 mm. maximum temperature: 80 ° C.
It`s the key ingredient in the world`s strongest magnets. They`re critical to computers, cell phones, hybrid cars, wind turbines, even tiny ear buds. Without neodymium, we`d be sunk!
Neodymium magnets (also known as “NdFeB”, “Neo” or “NIB” magnets) are permanent magnets made of neodymium, iron & boron. They are from the Rare-Earth magnet family and have the highest magnetic properties of all permanent magnets, stronger than Samarium Cobalt (SmCo), Alnico and Ferrite.
Neodymium magnets can jump together, pinch the skin and cause serious injuries. Neodymium magnets will leap and slam together from several inches to several feet apart. If you have a finger in the way, it can get severely pinched or even broken.

Trying to install a new fluro light, pull out old light to find 3 reds and 3 blacks 1 copper earth. What do I do to connect it up the right way??? When I pulled the old Fluro light out the 3 Reds were joined together with a connector ,two blacks were joined to one end of light wire, the other to the other end of the light wire,earth wire to the light case,the third black wire was connected to the wire from the ballast? Does this all make sense
ANSWER : No, this does not make sense but I have seen strange wiring before. There is power going from the light someplace else. Just connect it back up exactly as the old light was connected. It worked before so it will work again. If it works it is wired correctly. Without being there to check which wire was the hot wire and which was neutral it is impossible for me to say what is what. Make sure you connect the ground wire to the light chassis.

Paintball gun problem
ANSWER : First off, make sure it’s clean, and lubed with a quality oil made for paintball.If you’re sure the o-rings are good (as in relatively new) it’s pretty hard to tell just from looking as it doesn’t take a lot of damage to leak air.Try a different tank, just to be sure. Make sure it’s full.**** it. If that stops it there’s a clue. If it’s had some use it’s possible to have a bad/weak spring and the valve isn’t closing entirely. Make sure your velocity is less then 300fps. Check out your local airsmith or field and they should be able to get you squared away if none of that helps.Good luck!
Play hard, play safe, play with honor!

Paintballs keep blowing up in my tippmann 98 custom HELP!
ANSWER : It could be a combination of a number of things.. most likely it has to do with the type of paint you’re shooting; in regards to shell.. tippman guns are harder on paint therefore require a harder shell paint, also not all paintballs are exactly .68 caliber, meaning some a bigger and some are smaller.. could be that they’re slightly to big for the bore of you barrell
